Renovate: skip commit upgrades of otel-go

[dmathieu]

Description

#6144 was aiming to skip commit upgrades of renovate, but it appears that didn't do anything, since we still have the PRs: #6180

We should have renovate skip upgrades of otel-go if the dependency is on a commit, and only upgrade to the next release.

@dmathieu Please let me give this one a try, i might be wrong but based on the PRs if it requires modifying the renovate.json file to include rules that skip commit-based dependencies i could give it a try and you review
