Action fails on Windows because Chocolatey's servers are at capacity

[glatterf42]

Describe the bug

Beginning about a month ago, some of our CI tests on Windows began to fail quite frequently in the Run ts-graphviz/setup-graphviz@v2 step. See this recent run, for example.
The error always is always exactly this:

Run ts-graphviz/setup-graphviz@v2

We are not performing this step for our tests on Macos (see our workflow file) and on Ubuntu, installation happens from http://azure.archive.ubuntu.com/ubuntu instead of Chocolatey. This service seems to have become so popular that our CI regularly fails because their servers are at capacity.

To Reproduce

Take a look at our CI runs, this issue will appear at least once a week at the moment.
Alternatively, run your own CI tests that setup-graphviz on Windows. Maybe even several times a day to catch a period where their servers are at capacity.

Expected behavior

The download should work more reliably.

Additional context

Is there any way to install graphviz on Windows without relying on a flaky service?
