silence parser warnings after ruby upgrade

[phoet]

just upgraded to ruby 3.1.3 and slim-lint was issuing a warning:

warning: parser/current is loading parser/ruby31, which recognizes3.1.2-compliant syntax, but you are running 3.1.3. Please see https://github.com/whitequark/parser#compatibility-with-ruby-mri.

the link in the warning is not super helpful in regards to what's going on here or what to do with slim-lint, if anything needs to be done at all.

i'm using slim-lint extension for vs code on save, so this is quite distracting to have that message on save. it seems it can be fixed by gem install parser to latest dependency.

rubocop is just silencing those warnings: https://github.com/marcandre/rubocop-ast/commit/7081f7cae0326150b648c54a99e124998ab2bffb

Fixed in 0.24.0. Thanks!
