[DNM] Validate GHA Cache Miss

[sam-heilbron]

Description

Validate that a change with some go.mod updates, results in a github action cache miss

This is not meant to merge, just demonstrate behavior, and then be closed

Context

In #8545 we proved that cache hits work. This PR demonstrates that cache misses occur as well.

Testing steps

• Confirm that codegen step experienced a cache miss
• Confirm that GHA 1.14.x cache is not updated
• Confirm that a new cache entry exists for this PR
