Provide a detailed description of the proposed feature

Add an option to search to exclude deprecated formulas.
Something like brew search --no-deprecated <keyword>
Or the reverse, exclude by default and include with --deprecated?

What is the motivation for the feature?

Searching for Quick Look plugins to install but many have been deprecated – see #20732

How will the feature be relevant to at least 90% of Homebrew users?

What's recommended? Avoid installing deprecated formulas? So shouldn't these be excluded by default?

What alternatives to the feature have been considered?

I'm using brew info <name> to check each one individually = very time consuming!
