Upgrade to TypeScript v7

[caugner]

According to typescript-eslint/typescript-eslint#12521, typescript-eslint is unable to support TS 7, see this comment:

TS 7 is not supported by typescript-eslint and cannot be supported for the known future (due to TS 7 lacking an API).

This currently blocks us from upgrading to TypeScript 7.

See:

• build(deps-dev): bump typescript from 6.0.3 to 7.0.2 #1701
• chore(deps-dev): bump typescript from 6.0.3 to 7.0.2 browser-compat-data#30016
