Consider adopting --no-deps --no-build-isolation as default arguments for {{ PYTHON }} install script

[matthewfeickert]

The defaults for Python packages are currently to have a build script of

conda-smithy/conda_smithy/templates/meta.yaml.ci-skel.tmpl

Line 29 in b591810

script: "{{ PYTHON }} -m pip install . -vv"

but to ensure that all required build system dependencies are listed as host requirements, it would be nicer if the --no-deps --no-build-isolation arguments were adopted as well (as grayskull currently does), so

script: "{{ PYTHON }} -m pip install . -vv --no-deps --no-build-isolation"

c.f. discussion on conda/grayskull#582.

This is not needed as the build tool (e.g. conda-build, rattler-build) will be responsible for enforcing all the pip install options. c.f. conda/grayskull#582
