nix profile remove regression, cannot distinguish packages with the same name

[elikoga]

It is currently difficult for me to rebase cleanly #8956 due to a line like

nix profile remove --regex ".*foo-0.1" 2>&1 | grep 'removed 1 packages'

being impossible to write, due to packages of the same name not being distinguishable by the nix profile remove API, without explicitly handling the entire storepath with hash.

Maybe the nix profile remove --regex flag should search on the storepath? Maybe a new --regex-storepath flag?

I see #10166 reasoning is fine: "Question is: should we also regex-match on store paths? I think this can lead to unintended matching of hashes. So, probably not."

This is an argument for a new flag --regex-storepath for me
