[*/en] Fix typos across all files

[ghost]

I've run codespell and typos spell checkers against all english pages. I've carefully filtered out all false positives and manually applied fixes.

typos --exclude '*/' --format brief --sort > TYPOS
# review and make changes
fd -t f -d 1 | xargs codespell > TYPOS
# review and make changes

Please, make sure to skim through the changes and verify that this PR doesn't break any intended logic or introduce regressions.

• I solemnly swear that this is all original content of which I am the original author
• Pull request title is prepended with [language/lang-code] (example [python/fr] for Python in French or [java] for multiple Java translations)
• Pull request touches only one file (or a set of logically related files with similar changes made)
• Content changes are aimed at intermediate to experienced programmers (this is a poor format for explaining fundamental programming concepts)
• If you've changed any part of the YAML Frontmatter, make sure it is formatted according to CONTRIBUTING.md

@vendethiel hey, i've addressed the comment. there is also hanging #5436 where i've addressed the issue. I thought that i may have not made it clear that these PRs are ready so that's why they don't get any attention.
Or you just don't have time rn / we're waiting for more eyes to review?

Sorry, just fell through the cracks, there aren't many eyes looking at PRs and sometimes I open things in a tab to look at later and don't quite get to it.
The vim9script file should be safe to simply check out from master. I can do it if you'd prefer.

I can do it if you'd prefer.

Yeah, would be nice. Thanks
