#2211: Delete PythonUrlUpdater and related files

[Paras14]

This PR fixes #2211

Implemented changes:

• Deleted PythonUrlUpdater and its supporting classes PythonFile, PythonJsonObject and PythonRelease, together with PythonUrlUpdaterTest and its test resource.
• Removed the PythonUrlUpdater import and its entry in the updater list in UpdateManager.
• Background: since Python not available for Mac x64 #2100 / #2100: Resolve python versions via uv instead of ide-urls #2152, Python versions are resolved via uv python list (PythonRepository) instead of ide-urls, so the Python URL metadata is no longer used for installing Python and does not need to be crawled anymore.
• The python dependencies.json and security.json in ide-urls remain in use (findDependencies / findSecurity) and are untouched by this PR.
• Note: the removal of the existing Python version metadata in ide-urls is a separate PR (Delete python version metadata (devonfw/IDEasy#2211) ide-urls#45) in the devonfw/ide-urls repository, which must only be merged after this PR, because the nightly update-urls workflow would otherwise regenerate the deleted folders.

Testing instructions

1. Run mvn clean test, all tests pass and the build is successful.
2. Verify that UpdateManager no longer references PythonUrlUpdater and that the url-updater module still compiles and runs for the remaining tools.
3. After merge, the nightly Update URLS workflow no longer writes new Python versions into ide-urls; existing Python metadata stays untouched.

The project and the module are passing can be compiled and passed are tests. The UpdateManager.java doesn't create/use the PythonUrlUpdater.java and therefore no crawling regarding the URL defined in the PythonUrlUpdater.java should be made.

After fixing the CHANGELOG.adoc and updating the branch to the latest commit of main, this PR can move forward.

@Paras14 thanks for your PR. Great to do some cleanup. 👍
I have some formatting question that we should clarify but must not block this PR.
Also you should apply the review suggestion from @oanding-blrng
Then we can merge.

Deleted code is gone, nothing else to re-test.
