ci(eslint): ignore private/internal code for jsdoc rules (#6416)

**Related Issue:** N/A

## Summary

Prevents
[`eslint-jsdoc-plugin`](https://www.npmjs.com/package/eslint-plugin-jsdoc)
from complaining when an interface/function/class/etc is marked as
`@internal` or `@private` in its jsdoc block. We will need to go through
the code and appropriately mark a lot of our utils as `@internal`.
