False positive [unused_import_linter]

[tonyk7440]

It seems like when using a function inside a glue() call, this lintr doesn't recognise a function is being used.
An example

library(praise)

glue::glue(
  "Hi Team,
          
          {praise()}  

          All the best"
)

Which is flagged as
[unused_import_linter] Package 'praise' is attached but never used.

We should be able to reuse the logic from object_usage_linter() to extract usages from within glue() literals... Assigning to @IndrajeetPatil for now.
