CI: Fix macOS pipeline failure

[RickyC0626]

Changelog / Overview

Update ci.yml to update and upgrade brew if necessary before installing dependencies, and remove the unsupported dvisvgm.86_64-darwin package.

Motivation

CI macOS pipeline failure due to installation of a basictex package that no longer exists.

Exploring this avenue has also revealed that dvisvgm.86_64-darwin is no longer supported, as part of TeX Live 2021 release to support both ARM and Intel architectures. Instead, dvisvgm.universal-darwin will be used for MacTex, supporting macOS 10.14+. The legacy dvisvgm.x86_64-darwinlegacy binary folder will support macOS 10.6+, but it is only available with Unix install-tl.

LGTM, thank you for investigating and fixing the pipeline!

This is super helpful. Thanks for the hard work and speedy fix.

I'm not familiar with brew; is the update / upgrade / cleanup necessary given we're running this in a CI env, or was it more a temporary fix?

It was more of a temporary fix to solve the basictex issue, but it led to finding out about the legacy package. I think we can keep it as redundancy in case a similar issue occurs in the future.

How much time does it add to the build? If we compare it to #1200 's build, it looks like it adds 4 minutes across the board. That is a lot of time for a "might be helpful" change.

I do plan on working on caching as described in #824, for dependency-heavy packages such as ffmpeg to make the installation process faster.

[markromanmiller]

That will be helpful. For the time being, though - and assuming it still builds - can you take out that update line? Otherwise it LGTM.

Looks like that line was necessary

Sped up the time by a few minutes by only upgrading the brew packages we need.

Amazing, thank you!
