Enable eslint warning for type assertions (#1762)

## Description:

Enable eslint warning for
`@typescript-eslint/consistent-type-assertions`. While build warnings
are generally a discouraged pattern, we are actively working to drive
the number of warnings down to zero, at which point we will convert the
warnings to errors.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
- [ ] I have read and accepted the CLA agreement (only required once).
