chore: standardize type check job name to check-types (#9973)
### Description
This pull request standardizes the type checking task name to
`check-types` across all example repos. This is good so that new users
can learn one way and feel confident they will be able to run this
across all repos that need it.
### Testing Instructions
Running `turbo check-types` in `with-shell-commands` example
Running `pnpm check-types` in `with-typeorm` repo
Running `pnpm check-types` in `with-gatsby/apps/web`
Running `pnpm check-types` and `pnpm build` in `with-vue-next/apps/web`
