PR: Prevent Python variable validation to get current word and position when doing completions

[dalthviz]

Description of Changes

• Wrote at least one-line docstrings (for any new functions)
• Added unit test(s) covering the changes (if testable)

• Included a screenshot or animation (if affecting the UI, see Licecap)

When doing completions, the LSP provides also completions for file names. Files that start with number were not completed correctly since a validation for valid Python variables was being always made when getting the current word and position.

Looks good to me @dalthviz, thanks!

Please rebase to get the fixes to our tests in PR #20224, then I'll merge.

@ccordoba12 just for testing, I enabled an option that allows doing merge/rebases to PRs from the GitHub interface if the PR branch is not up to date with the PR base branch (Settings -> Always suggest updating pull request branches ). Maybe it could be worthy to keep it so contributors have a more easy time if they need to do a rebase or merge to update their PRs?

Good idea! I agree with that.

I also see that this change breaks test_kite_textEdit_completions. Since we don't support Kite anymore, please remove it.

Thanks @dalthviz!
