Fix Scorecards GitHub Action
Fixes sudden failure reported in https://github.com/pandas-dev/pandas/issues/48566#issuecomment-1296174657.

Bumps ossf/scorecard-action to v2.0.6, fixing an unexpected breaking change in upstream API.

this doesn't currently run on PRs - should it?

and does
```
# if: github.repository == 'pandas-dev/pandas'  # don't run on forks
```
need to be commented out? A mistake. I've just pushed a new version undoing that comment and some accidental linting.

Also, the Action is currently still in development for PRs. I'll be sure to return here when it is made available. Thanks @pnacht  @pnacht this is still failing https://github.com/pandas-dev/pandas/actions/runs/3381132789/jobs/5614699256 shall we remove this until it's a bit more stable? @MarcoGorelli maybe we can add `continue-on-error: true` for this job? I think that's already the case - even if it fails, it's not blocking the other jobs from running Hey everyone, thanks for letting me know. This one's a bit more surprising; I just created a [fork](https://github.com/pnacht/pandas/actions) of the project and the Action is running fine there... other projects with the Action also aren't having this issue.

I've also noticed it's [working again](https://github.com/pandas-dev/pandas/actions/workflows/scorecards.yml)... most odd.
