Fixes #36587 - rename Host - Applicable Errata report

[ianballou]

• ...and fix comment typos

Renames the applicable errata report since it no longer only reports on applicable errata.

Also, remove some odd characters that look like whitespace in GitHub but really aren't. They were breaking syntax highlighting in Foreman.

To test:

1. Create a report template called "Host - Available Errata"
2. Apply this PR and run the migration
3. Ensure that the report template you created is backed up under a different name
4. Ensure that the "Host - Available Errata" report has what the "Host - Applicable Errata" report used to have
5. Ensure that the "Host - Applicable Errata" report is gone
6. Ensure that the syntax highlighting is not broken for "Host - Available Errata" or "Host - Registered Content Hosts"
