Fix map type name warnings due to unused block

[bkuhlmann]

Why

Hello. 👋 I'm seeing the following strict_unused_block category of warning show up when launching an IRB session:

/Users/bkuhlmann/.cache/frum/versions/3.4.1/lib/ruby/gems/3.4.0/gems/rbs-3.8.1/lib/rbs/environment.rb:793: warning: the block passed to 'map_type_name' defined at /Users/bkuhlmann/.cache/frum/versions/3.4.1/lib/ruby/gems/3.4.0/gems/rbs-3.8.1/lib/rbs/types.rb:18 may be ignored

The problem is map_type_name doesn't make use of a block and should be refactored so the warnings goes away.

How

To recreate, run:

export RUBYOPT="-W:strict_unused_block"
irb

Notes

• RBS: 3.8.1

Thanks for fixing these warnings. 🙇 Would it be possible to get a new version of this gem published so I could pick up the changes? There hasn't been a new version release since December of last year.
