Subject: [PATCH] fix: escape title when searching for comment line

If regex characters are part of the title (for
example, parentheses), then this breaks the ability
to find the comment line when trying to insert
the issue URL. This commit escapes the title
to fix this problem.

Closes github.com/alstr/todo-to-issue-action#226
