Proposed Changes

feat(show): Default --all to true and deprecate

So that we expose to the user all versions of a pkg_path from the catalog. There's no functional change for the non-catalog code path because pkgdb only ever knows about a single version.

It looks like this defaulted to false because the original design accounted for matching multiple pkg_paths and would later include stabilities:

• https://github.com/flox/product/blob/main/requirements/archive/search-v1.md#design

I've left the flag, hidden it, and added a deprecation warning, in case anyone happens to be using it currently. This can be removed in future releases.

feat(show): Output one version per line

This tidies up the output and will make it easier to copy/paste a specific result. In turn, stop duplicating the pkg_name, which is already printed on the line above with the package description.

Release Notes

• flox show improvements
  • --all is now the default and the flag has been deprecated.
  • outputs one version per line.

product verified - looks good on a branch! (non-code review)

I think the output is pretty much tested as integration tests now. Noting that we can probably make that a unit test without a lot of effort I'll go queue this anywaysince it does what the ACs called for

The example output in the man page needs to be updated

Darn, I checked that the flag wasn't there, but forgot when it came to the output format. Followed up in https://github.com/flox/flox/pull/1451
