release: 1.5.0-alpha.1 (#154)

* codegen metadata

* chore(internal): move mypy configurations to `pyproject.toml` file

* feat(api): api update

* chore(tests): simplify `get_platform` test

`nest_asyncio` is archived and broken on some platforms so it's
not worth keeping in our test suite.

* chore(internal): update pydantic dependency

* chore(types): change optional parameter type from NotGiven to Omit

* chore: do not install brew dependencies in ./scripts/bootstrap by default

* feat(api): manual updates

* release: 1.5.0-alpha.1
