[Feature] puro prepare <envName> to download artifacts

[Vonarian]

Currently, each Flutter environment upgrade forces a build artifact download, e.g flutter build apk downloads release, debug, etc. artifacts.
I have a long one-liner to do this flutter build apk; flutter build web; ...
The command puro prepare master can run all the required commands and download the artifacts for the master channel.

Is this different from precache at all?

I believe the point is doing a precache, yes.
flutter upgrade will download the artifacts but puro upgrade does not.
I also looked into Puro Commands and I didn't find a command to do this, hence the issue and PR :)

puro -e <envName> flutter precache would achieve the same thing, I would like to just have it precache by default when installing a new environment though.

Well, fun fact is I didn't know flutter precache existed O.O
puro prepare could be an alias for this command tho:
puro -e stable flutter precache vs puro prepare stable.
(Or puro precache)
