pypiPackages property Null safety

Map<String, String>? pypiPackages
read / write

Custom Python Package Index (PyPI) packages to be installed in the environment.

Keys refer to the lowercase package name such as "numpy" and values are the lowercase extras and version specifier such as "==1.12.0", "[devel,gcp_api]", or "[devel]>=1.8.2, <1.9.2". To specify a package without pinning it to a version specifier, use the empty string as the value.

Optional.
