Add a resolvePath or absPath function

[ssbarnea]

Description

Current function templates do not allow someone to resolve a path like like FOO=/foo/bar/zzz with ...

I looked at relPath and the other path related functions but I found none that can resolve paths (ideally even resolving symlinks).

Current workaround is to rely on bash to do it.

Do any of these help? https://sprig.taskfile.dev/
