fix: typos across specs

[nschonni]

This probably needs to get re-submitted in smaller chunks. I went across the repo using cSpell and fixed word-by-word creating this large PR.
Possible alternate approach would be to collapse this down and then re-submit by spec folder.

If going with the flattened folder-by-folder, should the various issue* files be ignored? There were some with incorrect key names.

Wow, this must have taken a long time to get right. Thanks for putting it together! No need to split across specs, it's actually easier to review like this. Want to confirm s/targetted/targeting/ with @tabatkins, but aside from that everything else looks correct. The one bit that needs adjustment is that in the issues-* files, removing a letter from a key needs to add a space so that the values all continue to line up. :)

I had separately pulled out the "Typogrraphy" one, and @svgeesus pointed out that some of the older specs like css-fonts-3 have hit the point were they shouldn't really be touched.
If you want to comment inline on any specific ones that should be pulled or reformmated, I can try and rebase out the particular changes

If you can merge in those whitespace fixes, I can merge in your PR.

You need to unmark it as a draft for me to merge.

[nschonni]

@fantasai I'm un-marked it as draft, but I'm not sure what parts might still need to be rebased out because they've hit CR now

[fantasai]

None, it merged cleanly. :) Thanks~
