Upgrade to 1.22.4

[jcollado]

Upgrade to chalice 1.22.4.

Latest version uses a more recent version of pip that fixes this security issue:
pypa/pip#9827

This is reported by safety as follows:

+==============================================================================+
| pip | 20.0.2 | <21.1 | 40291 |
+==============================================================================+
| Pip 21.1 stops splitting on unicode separators in git references, which |
| could be maliciously used to install a different revision on the repository. |
| See: pypa/pip#9827. Additionally, pip 21.1 |
| updates urllib3 to 1.26.4 to fix CVE-2021-28363.

@sodre Any update on this?

[sodre]

@jcollado, this looks good. Would you like to become a maintainer of this package?

[jcollado]

Thanks for getting back to me @sodre. I don't really have experience as package maintainer, but you can add me if you wish.
