Fix: update and escape a handful of templates

[scottbarnes]

We run extract/i18n-messages extract by default now, but we need to get the master branch in a state where the command can run cleanly, or the files in this commit will get flagged with any commit that makes an i18n change.

This seems to be confusing people.

Edit: I double checked by adding another commit with an i18n text change and no accompanying update to messages.pot within the PR. on push, pre-commit ran, failed because message.pot changed by way of the pre-commit hook, added the updated messages.pot to the PR, ran again, and succeeded. This is evidence, though not entirely conclusive, that it may fix things for, e.g., #9246.

Testing

• Get on the current master branch.
• Make a change to to some i18n text. E.g.:

diff --git a/openlibrary/templates/type/edition/compact_title.html b/openlibrary/templates/type/edition/compact_title.html
index a9b60b517..189f5fb04 100644
--- a/openlibrary/templates/type/edition/compact_title.html
+++ b/openlibrary/templates/type/edition/compact_title.html
@@ -6,7 +6,7 @@ $def with (book_title, edit_url)
     <a
       class="linkButton linkButton--large"
       href="$edit_url"
-      title="$_('Edit this page')"
+      title="$_('Edit this page please')"
       data-ol-link-track="CTAClick|StickyEdit"
       rel="nofollow"
     >$_("Edit")</a>

Run pre-commit to generate the POT files, and see that it both fails and generates a new i18n/messages.pot:

❯ pre-commit run generate-pot --all-files

changes lgtm though I think we'll need to rebase or resolve conflicts before proceeding due to other recent i18n changes merged
