Validate Python interpreter version for native server

[dhruvmanila]

Summary

I'm not sure why this check was removed looking back at #431, but this validation should be done for both native server and ruff-lsp. Both uses a Python script which requires Python 3.7 or later and ruff in general also supports 3.7 and later.

Without this change, if someone were to use Python 3.6, the extension would give the following error:

2024-07-05 09:26:21.378 [error] Error while trying to find the Ruff binary: Error: Command failed: /Users/dhruv/.pyenv/versions/3.6.15/bin/python /Users/dhruv/work/astral/ruff-vscode/bundled/tool/find_ruff_binary_path.py
Traceback (most recent call last):

    elif sys.platform == "darwin" and sys._framework:

Test Plan

The above error still occurs and the fix for that is in a follow-up PR (#517).

Using the below settings:

{
  "ruff.nativeServer":true,
  "ruff.interpreter": ["/Users/dhruv/.pyenv/versions/3.6.15/bin/python"]
}

The logs shows that the version isn't supported:

2024-07-05 09:27:38.086 [error] Python version 3.6 is not supported.
2024-07-05 09:27:38.086 [error] Selected python path: /Users/dhruv/.pyenv/versions/3.6.15/bin/python
2024-07-05 09:27:38.086 [error] Supported versions are 3.7 and above.

Suggested change

	interpreter &&
	interpreter.length > 0 &&
	interpreter?.length > 0 &&

[MichaReiser]

or does typescript complain that the left isn't a number. In that case I would write interpreter != null && interpreter.length > 0. We should probably enable the lint rule to enforce != instead of on truthiness checks.

[dhruvmanila]

Yeah, the compiler complains. I'll change it to use explicit null checks but I can't find the lint rule which corresponds to that in https://www.typescriptlang.org/tsconfig/.

I think it's https://typescript-eslint.io/rules/strict-boolean-expressions/
