1. - Fix an error when using heredoc with non-word delimiters …

   I've found whitequark#986 regression in the following RuboCop CI matrix:
   https://github.com/rubocop/rubocop/actions/runs/7437077900/job/20234293932?pr=12598
   
   So, whitequark#986 was not a sufficient fix. This PR fixes an error when using heredoc with non-word delimiters:
   
   ```ruby
   <<~'+'
     foo
   +
   ```
   
   The following repro test have been newly added:
   
   ```console
   $ bundle exec ruby -Itest test/test_lexer.rb
   (snip)
   
     1) Error:
   TestLexer#test_heredoc_plus_character:
   RegexpError: target of repeat operator is not specified: /+\z/
