build: add yarn script alias for tsc

Adds a `yarn run` alias for the `tsc` binary. Since we have
multiple versions of TypeScript installed, Yarn can pick
another version (e.g. from `typescript-4.2`) for linking
the `tsc` binary. This is unexpected because `yarn tsc` should
resolve to the TypeScript version that is not installed through
a Yarn alias. Changing the order in the Yarn lock file does not
help, and it seems expected in the context of Yarn which does not
know which package (regardless of alias or not) to prefer.
