The changes in this PR can be approved as-is. Note (mostly to self): additional steps are needed to ensure these changes take effect in CI:

• Add env var to CI job environment
• Remove notebook cell tag that causes the cell that would be affected by the reduced runtime to be skipped
• Enable RE DoubleLoopOptimization to run on Linux (Fix issues due to capitalization sample-data#1)
