IGNITE-27645 Python DB API: Fix version generation

[isapego]

https://issues.apache.org/jira/browse/IGNITE-27645

Currently, for any version like 3.2.0-beta1, 3.2.0-beta2, 3.2.0 we will generate the same version for the python DB API package - 3.2.0. This won't do as we can not upload multiple packages with the same version. So this patch addresses it and generates appropriate versions like 3.2.0b1 or 3.2.0b2 in cases like this.

See https://packaging.python.org/en/latest/discussions/versioning/ for details

Also removed unused code for wheels generation using Docker.

Pull request overview

This PR fixes Python version generation for the DB API by implementing proper conversion to Python's version format (PEP 440) and removes unused Docker-based Gradle build tasks for wheel creation.

Changes:

• Adds pythonProjectVersion() function to convert project versions to Python-compatible format (e.g., "3.2.0-alpha1" → "3.2.0a1")
• Replaces simpleProjectVersion() with pythonProjectVersion() in updatePythonVersion() to preserve pre-release identifiers
• Removes Docker plugin dependency and all Docker-related imports, variables, and tasks (manylinux wheels, Windows wheels, source distribution tasks)

The conditional checks use the original addition variable instead of the lowercased pythonAddition variable. This means the checks will fail for uppercase pre-release identifiers (e.g., "ALPHA", "BETA", "PATCH"). The condition should check pythonAddition.startsWith() instead of addition.startsWith() since the replacements were made on the lowercased version.

Suggested change

	def pythonAddition = addition
	.toLowerCase()
	.replace("alpha", "a")
	.replace("beta", "b")
	.replace("patch", "p")
	if (addition.startsWith("alpha")
	|| addition.startsWith("beta")
	|| addition.startsWith("patch"))
	def lowercasedAddition = addition.toLowerCase()
	def pythonAddition = lowercasedAddition
	.replace("alpha", "a")
	.replace("beta", "b")
	.replace("patch", "p")
	if (lowercasedAddition.startsWith("alpha")
	|| lowercasedAddition.startsWith("beta")
	|| lowercasedAddition.startsWith("patch"))

The tokenize('-') method splits on all occurrences of '-', not just the first one. If a version string contains multiple dashes (e.g., "3.2.0-alpha-1"), the destructuring assignment will fail because it expects exactly 2 elements but will receive more. Consider using split('-', 2) or handling the first dash only with indexOf('-') to safely handle multi-dash version strings.

Suggested change

	def (simple, addition) = version.tokenize('-')
	def dashIndex = version.indexOf('-')
	def simple
	def addition
	if (dashIndex == -1) {
	simple = version
	addition = null
	} else {
	simple = version.substring(0, dashIndex)
	addition = version.substring(dashIndex + 1)
	}

The opening brace is placed on its own line, which is inconsistent with the style used elsewhere in this file where braces are typically on the same line as the conditional statement. For consistency, consider moving the opening brace to the same line as the last condition or the first condition.

Suggested change

	|| addition.startsWith("patch"))
	{
	|| addition.startsWith("patch")) {

The version conversion logic does not handle release candidate versions properly. According to PEP 440, release candidates should be formatted as "3.2.0rc1" (without a dot separator), similar to alpha and beta. However, versions like "3.2.0-rc1" will be converted to "3.2.0.rc1" (with a dot), which is not the standard format. Consider adding support for "rc" by including it in the replace logic and the startsWith check.
