Bumps urllib3 from 1.26.8 to 1.26.20.

Release notes

Sourced from urllib3's releases.

1.26.20

🚀 urllib3 is fundraising for HTTP/2 support

urllib3 is raising ~$40,000 USD to release HTTP/2 support and ensure long-term sustainable maintenance of the project after a sharp decline in financial support for 2023. If your company or organization uses Python and would benefit from HTTP/2 support in Requests, pip, cloud SDKs, and thousands of other projects please consider contributing financially to ensure HTTP/2 support is developed sustainably and maintained for the long-haul.

Thank you for your support.

Changes

  • Fixed a crash where certain standard library hash functions were absent in FIPS-compliant environments. (#3432)
  • Replaced deprecated dash-separated setuptools entries in setup.cfg. (#3461)
  • Took into account macOS setting ECONNRESET instead of EPROTOTYPE in its newer versions. (#3416)
  • Backported changes to our tests and CI configuration from v2.x to support testing with CPython 3.12 and 3.13. (#3436)

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
