Fix for #5423

[katzchang]

$ npm run fix:htmltest-config

> fix:htmltest-config
> scripts/htmltest-config.sh

Warning: Unrecognized htmltest IgnoreDirs config from front matter in file 'content/pt/docs/_index.md': IgnoreDirs: {}

When I try to run fix:htmltest-config, I get this error. After deleting the IgnoreDirs: {} statement in content/pt/docs/_index.md, the problem goes away.

@chalin Do you think okay to delete it?

That should have been caught earlier. I need to fix the CI scripts first. Let me do that before approving this PR.

Waiting for the following to get merged, then we'll rebase this PR:
