Support regex search queries

Difference: Upstream allows "or"-ing search terms with |. But scoop-search doesn't.

this is extremely handy while migrating from manual installs to scoop installs. as i can paste same expression in "bulk crap uninstaller" and in "scoop-search" to compare the offerings

It seems like this is due to scoop search actually accepting regexes, not raw strings. I will rename this issue to reflect full regex support. It is unclear whether I will get to it though, seems like there is no good Regex support in zig, I would have to link against some external libraries.
