Installation process could be more verbose

[MichaelChirico]

I was trying to peer through the install logs when thinking about Rdatatable/data.table#6528 and noticed that it's not clear from the logs what {atime} is doing vs. what the rest of the GHA process is doing.

I think it would be helpful to ensure {atime} makes a bit more noise, e.g. leading off the install chain with a nicely-formatted message along the lines of "atime is installing the following versioned copies of {package}: ".

yes that would be nice.
right now the logic about deciding what package to install happens inside atime_pkg -> atime_versions -> atime_versions_exprs -> atime_versions_install
we would have to do a re-design which introduces a "analyze what we want to do" phase before the current "do some stuff" phase

I think for now even a "Beginning atime installation of pinned versions of {package}..." would be an improvement
