fix(pyproject.toml): loose requests pgk and remove urllib3 as dependency

[karimelhajoui63]

Hi,

We can see that when we install the v2.15.3 from pipenv, then print the graph of dependencies:

pipenv install python-keycloak==2.15.3
pipenv graph

we have a conflict on the urllib3 lib :

python-keycloak==2.15.3
  - deprecation [required: >=2.1.0,<3.0.0, installed: 2.1.0]
    - packaging [required: Any, installed: 23.1]
  - python-jose [required: >=3.3.0,<4.0.0, installed: 3.3.0]
    - ecdsa [required: !=0.15, installed: 0.18.0]
      - six [required: >=1.9.0, installed: 1.16.0]
    - pyasn1 [required: Any, installed: 0.5.0]
    - rsa [required: Any, installed: 4.9]
      - pyasn1 [required: >=0.1.3, installed: 0.5.0]
  - requests [required: >=2.28.2,<3.0.0, installed: 2.20.0]
    - certifi [required: >=2017.4.17, installed: 2022.12.7]
    - chardet [required: >=3.0.2,<3.1.0, installed: 3.0.4]
    - idna [required: >=2.5,<2.8, installed: 2.7]
    - urllib3 [required: >=1.21.1,<1.25, installed: 1.24.3]     # <1.25
  - requests-toolbelt [required: >=0.10.1,<0.11.0, installed: 0.10.1]
    - requests [required: >=2.0.1,<3.0.0, installed: 2.20.0]
      - certifi [required: >=2017.4.17, installed: 2022.12.7]
      - chardet [required: >=3.0.2,<3.1.0, installed: 3.0.4]
      - idna [required: >=2.5,<2.8, installed: 2.7]
      - urllib3 [required: >=1.21.1,<1.25, installed: 1.24.3]   # <1.25
  - urllib3 [required: >=1.26.14,<2.0.0, installed: 1.24.3]     # >=1.26.14

So I:

• removed the urllib3 direct dependence, since it doesn't seem to be used in this code base
• allowed the use of requests package starting from v2.20.0 for more compatibility with other packages

The tests aren't green, but this doesn't seem to be related with this PR since even when I revert: everything, the errors where still here.

Any info on what is going on with these latest tests ?

Hi @karimelhajoui63

Thanks a lot for this change :) It's been on my todo list for a while. LGTM, the tests should now pass on the master branch :)
