Fix code scanning alert - Call to requests without timeout

[aholmes]

This appeared during the BL_Python to Ligare rename and has been previously addressed.

While this area of code is used in a trusted context and is not a security concern, it would still behoove us to add a timeout to calls to requests methods. This is seen in src/identity/build/lib/Ligare/identity/SAML2/__init__.py:41.
