Wildcard translation key specifiers

[MMK21Hub]

It would be nice to be able to use wildcards to select translation keys to apply a transformer.

For example, MC-203095 affects quite a few translation strings:

• commands.experience.add.points.success.single
• commands.experience.add.points.success.multiple
• commands.experience.add.levels.success.single
• commands.experience.add.levels.success.multiple
• commands.experience.set.points.success.single
• commands.experience.set.points.success.multiple
• commands.experience.set.levels.success.single
• commands.experience.set.levels.success.multiple
• commands.experience.query.points
• commands.experience.query.levels

This could be expressed with something like this:

• commands.experience.*.*.success.*
• commands.experience.query.*

Much more concise!
