Fixes # .

Summary/Motivation:

We continue to see intermittent test failures (primarily on win/3.11) where conda hangs indefinitely trying to solve the environment while installing SCIP. As resolving this issue will likely require a SCIP release, this PR updates the process we use to conda install optional packages (solvers) to enforce a 5-minute timeout when installing each package.

Timing out on the install will NOT fail the build.

Changes proposed in this PR:

• Add a 5-minute timeout when attempting to install optional solvers with conda
