chore(pr-check-fix): Fix PR check (again)

[qdm12]

Sorry the previous PR got merged pre-maturely 😅

Changes

• Remove \r characters (Microsoft, really!??)
• Display new lines as \\n in error messages so it's clearer
• Make title regex more flexible
  • Allow - and _ in category
  • Allow -, _ and in subcategory (inside parentheses)
  • Allow at least one character to be any character at the end of the title (e.g. fullstop .)

Tests

go test -run ^Test_CheckPRDescription$ github.com/ChainSafe/gossamer/lib/utils
