CompatHelper: bump compat for OrderedCollections to 2 for package docs, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the OrderedCollections package from 1 to 1, 2 for package docs.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.

Benchmarks @ 25a836e

Performance Ratio: gradient time divided by log-density time.

For very small models these ratios are noisy across runs and machines; raw primal and gradient timings are more reliable. The benchmarks are aimed at DynamicPPL developers and mainly catch obvious allocation or type-stability regressions. See benchmark notes for details.
