This PR fixes an issue where `grind` did not display deprecation
warnings when deprecated lemmas were used in its argument list.
The fix adds explicit calls to `Linter.checkDeprecated` after resolving
theorem names in both `processParam` (for theorem arguments) and
`elabGrindParams` (for the `-` erase syntax).
