style[eve]: remove unused imports and fix typos

[romanc]

Description

Small cleanup PR in the eve framework:

• Removes a stale .gitignore file. As far as I understood from the git history, earlier versions of this codebase had many .gitignore files in many places. Looks like this one is a leftover from a previous time.
• Remove a couple of stale includes. The language server marked them as unused and since tests still pass, I guess we really don't need them anymore.
• Fixed a couple of typos in comments
• Fixed two typos in the github PR template

Requirements

• All fixes and/or new features come with corresponding tests.
  N/A: neither fixes nor new features
• Important design decisions have been documented in the appropriate ADR inside the docs/development/ADRs/ folder.
  N/A

I'm sorry for the late reply, I somehow forgot to add my question before submitting my previous review. This was the missing question.

Why are those removed? IIRC those imports are here just to mimic the deprecated aliases in typing for older python versions. Once we drop support for 3.8 and 3.9 (hopefully in a matter of weeks) we should delete all these aliases, but until then I think we should keep them for consistency.

[romanc]

I removed them because the vscode language server for python marked them as unused (unlike others in that category). Since 3.8 and 3.9 versions of tests still pass, they might actually be unused. However, I didn't see that they are part of a code block guarded for 3.9 only. If the plan is to drop support for 3.8 and 3.9 in the next weeks, I agree, that there's no need to change anything here since we'll just get rid of the whole block with that PR. I'll revert my changes here 👍
