Bump parser current_version patch version for ruby 3.4

[navidemad]

Fix #1056

I was getting this warning from the gem i18n-tasks:

warning: parser/current is loading parser/ruby34, which recognizes
3.4.0-compliant syntax, but you are running 3.4.1.
Please see https://github.com/whitequark/parser#compatibility-with-ruby-mri.

I made the following PR:
glebm/i18n-tasks#613

But perhaps fixing it in the parser repository is better.
