Improve error message for scope

[olivroy]

Also fixing some errors I introduced. When linking only to a help page, one should use topic, not help.

Also, I was wondering if it was possible to run styler, but only for quotes, i.e. changing '' to ""?

This is how benchmark results would change (along with a 95% confidence interval in relative change) if dbaa169c3552d400489bd15765f2de0a429fdbcb is merged into main:

•   :ballot_box_with_check:cache_applying: 166ms -> 169ms [-1.33%, +4.24%]
•   :ballot_box_with_check:cache_recording: 556ms -> 558ms [-0.63%, +1.22%]
•   :ballot_box_with_check:without_cache: 1.05s -> 1.05s [-0.65%, +0.72%]

Further explanation regarding interpretation and methodology can be found in the documentation.

Thanks for your suggestion, I applied them + a couple extra things here and there!

• arg_match0() for performance, change link in package doc and inherit package doc title from DESCRIPTION. + add qmd in alpha order where applicable
