Subject: aux/workflow/TODOs.sh: Remove dependency on Perl

I've replaced the Perl usage for doing regexes with plain sed.

Implements #task-bf65e50a-b424-9fce-ba8e-fcd6b3bf1c7a.

Also:
- README.md: remove Perl from the list of tools required;
- po/LC_MESSAGES/README.en.md/*.po: translate the update on required
  tools;
- aux/guix/manifest.scm: remove Perl package.
