Resolve dependencies and rebuild, squash warnings

[bollwyvl]

This resolves the dependencies updates suggested by #77 and #69, but also runs the build so might be simpler than taking those.

This should also fix #78 (once released).

[bollwyvl]

The upgrade reveals some new warnings:

https://github.com/conda-incubator/setup-miniconda/actions/runs/291485813

Please run using "bash" or "sh", but not "." or "source"\n/home/runner/work/_temp/47b7cea6-d0a4-4996-8834-c36d4302b2f5: line 13: return: can only `return' from a function or sourced script

Please run using "bash" or "sh", but not "." or "source"\n

as well as of course the conda upgrade... will take a look into squashing them...

[bollwyvl]

looks like that's just some juiced-up warnings... the only thing i've seen is to redirect the output, e.g. bash miniconda.sh > /tmp/installer-output. The installer output is not very interesting, anyway, so maybe we only show it in case of error?

[bollwyvl]

ah, i see execute has an error swallowing mechanism, will add to that...

[goanpeca]

Looks great, thanks @bollwyvl

[goanpeca]

Are we good to merge after tests pass?

[bollwyvl]

I'd like to get all the errors we know about today squashed, since that's what people see... so some approach from #58 (comment) would be good...

[bollwyvl]

Ok, I have the ones from #79 (comment) squared away.

We just need to pick (some) approaches for the conda update notify, happy to do them here!

[goanpeca]

Ping me or merge when ready @bollwyvl the overall approach looks good, so thanks again :-)

[bollwyvl]

@goanpeca Ok, the bootstrap condarc does the trick. It gets overwritten if the user specifies a conda file, which is fine, i think, at least they will know it can be used, and can control. I'd say this is ready to go!

[bollwyvl]

the only warning this action doesn't emit is the only_use_tar_bz2 on windows with its old conda... but then, I'm not super confident on caching on windows at present, anyways...

[bollwyvl]

Pushed for #79 (comment) (Other Shells should have no warnings)

[bollwyvl]

Yep, that did it: we're down to just first-party warnings, not planning to do anything else here...

[bollwyvl]

Hooray!

[bollwyvl]

So can this already be tested out, or do we need a release?

[bollwyvl]

Trying out @master, it looks like the explicit stuff was never tested on windows, and therefore doesn't work... sigh.
