test/validators.test.js:1988

The Bengali (bn-IN) locale is being tested but was not mentioned in the PR title or description as one of the new Indic locales being added. This test appears to be for an existing locale rather than a newly added one.

You'll be mentioned in the release notes of the next release (which I will draft after #2574 is merged) . GitHub mentions you as 'Contibutor' in new PRs and comments, but that is not something we control. GitHub does that last bit automatically
