[Housekeeping] Remove deprecated numpy aliases

[eapolinario]

Describe the issue

A few aliases defined in numpy were deprecated in v1.20.0 and finally removed in v1.24.0 (check Deprecations in https://github.com/numpy/numpy/releases/tag/v1.20.0).

We should remove the mentions to those deprecated aliases from the FlyteSchemaTransformer.

What if we do not do this?

Users who install numpy>=1.24.0 will see this error in flytekit:

/tmp/tmp.pgqfAvNZOC/venv/lib/python3.10/site-packages/flytekit/types/schema/types.py:324: FutureWarning: In the future `np.bool` will be defined as the corresponding NumPy scalar.  (This may have returned Python scalars in past versions.

It looks like one of these changes has already been made in the PR flytekit#1557

-        _np.bool: SchemaType.SchemaColumn.SchemaColumnType.BOOLEAN,  # type: ignore
+        _np.bool_: SchemaType.SchemaColumn.SchemaColumnType.BOOLEAN,  # type: ignore

I've verified that all the numpy types referenced in FlyteSchemaTransformer are valid for numpy version 1.26.4. So maybe the only work that needs to be done here is to relax the version constraint on numpy?
