Fixes #16188

This was caused by some refactoring of Formula.all a few months ago.

In this case, --eval-all was not propagated to the Formula.all command which caused a few different description related commands not to work.

Broken commands:

• brew search --desc --eval-all TERM
• brew desc --search --eval-all TERM
• brew desc --descriptions --eval-all TERM

These commands will fail if the cache store has not already been built locally since this specific method call is only needed when building the cache store not accessing it. The cache store file can be found at:

"$(brew --cache)/descriptions.json"

Before:

$ brew desc --search --eval-all test
==> Formulae
Error: Calling Formula#all without --eval-all or HOMEBREW_EVAL_ALL is disabled! There is no replacement.
$ brew search --desc --eval-all test
==> Formulae
Error: Calling Formula#all without --eval-all or HOMEBREW_EVAL_ALL is disabled! There is no replacement.
$ brew desc --description --eval-all test
==> Formulae
Error: Calling Formula#all without --eval-all or HOMEBREW_EVAL_ALL is disabled! There is no replacement.

After these changes, the file should be created and the commands should work as expected.
