Metaparams should not be downcased

[Clebam]

Describe the Bug

dsc_base_prodiver.rb canonicalization converts everything to downcasen including metaparams which results in a comparison failure

dsc_scheduled_tasks:
  'patch_management':
    dsc_ensure: 'present'
    dsc_enable: true
    #//stuff
    require: File[D:/Temp/TOTO.txt] # Note the uppercase characters

Error: Failed to apply catalog: Could not find dependency File[d:/temp/toto.txt] for Dsc_scheduledtask[patch_management]

Here the characters are downcased

Expected Behavior

The metaparams should preserve their casing

Steps to Reproduce

Steps to reproduce the behavior:
Use a require on a resource

Environment

Windows Server 2019

Additional Context

I pinpointed the issue to this piece of code : https://github.com/puppetlabs/ruby-pwsh/blob/main/lib/puppet/provider/dsc_base_provider/dsc_base_provider.rb#L83

It better be r.select so that the metaparams keep the original casing
