build: Update lower bounds to tensorflow v2.7.0, jaxlib v0.1.61

[matthewfeickert]

Description

• tensorflow v2.6.5 restricts numpy to numpy~=1.19.2 but numpy.typing was not added until numpy v1.20.0. For typing of the NumPy backend to work as added in PR feat: Add typehints to pyhf.tensor #1940, tensorflow v2.7.0+ is required, where tensorflow relaxes numpy constraints to numpy>=1.14.5.

• jaxlib v0.1.60 required numpy>=1.12,<1.20 but jaxlib v0.1.61 requires numpy>=1.16.

For the PR Assignees:

• Summarize commit messages into a comprehensive review of the PR

* Update lower bound of the supported tensorflow versions to v2.7.0 to ensure
  numpy v1.20.0+ is available.
   - numpy.typing is needed for PR #1940 and was added in numpy v1.20.0.
   - tensorflow v2.6.5 restricts numpy to 'numpy~=1.19.2' and tensorflow v2.7.0
     relaxes numpy constraints to 'numpy>=1.14.5'.
* Update lower bound of the supported jaxlib versions to v0.1.61.
   - jaxlib v0.1.60 required 'numpy>=1.12,<1.20' and jaxlib v0.1.61 relaxes this
     to 'numpy>=1.16'.
* Update tests/constraints.txt to use tensorflow==2.7.0 and jaxlib==0.1.61.

You could alternatively hide numpy.typing in the TYPE_CHECKING and install a newer version of numpy just for mypy.

This is true, but if we bump these two lower bounds then we also unlock numpy from being kept below v1.20 which allows for more flexibility in a lot of environment solves. So I personally don't mind bumping these if you're okay with it.
