Run the test suite with GitHub actions.

Run the test suite using GitHub actions.

Other minor improvements:

• Use UV_PYTHON_PREFERENCE=only-system (as recommended in uv docs, brings a minor speedup).
• Fix a test case (OpenSSL now requires -CAFile for verification).
• Add Dockerfile to test running on different distributions.
• Remove .travis.yml file (no longer needed).

Note that the Dockerfile can be used to indeed verify that OpenSSL 3.0.10 and oscrypto have a problem:

On Ubuntu 24.04:

$ docker build --build-arg IMAGE=ubuntu:24.04 -t test .
...
$ docker run --rm -it test 
OpenSSL 3.0.13 30 Jan 2024 (Library: OpenSSL 3.0.13 30 Jan 2024)
$ docker run --rm -it test 
...
.venv/lib/python3.12/site-packages/oscrypto/_openssl/_libcrypto_cffi.py:44: LibraryNotFoundError

While on Ubuntu 22.04:

Independently of the contents, can we switch the default merge behavior to rebase and merge? History already has a lot of pointless merge commits. Obviously a matter of preference, but let me know what you think.

Thanks for the reminder - I have disabled the merge option, only squash and rebase merging are available.

[mathiasertl]

Hi! Can we get this merged? Kr, Mat

[mathiasertl]

Same question again, @kislyuk?

Kr, Mat

[kislyuk]

LGTM, thanks. Merging. Just to clarify, the Dockerfile is not directly used in GHA, right?

[mathiasertl]

Yes exactly. But it does allow you to easily run it on different distro versions locally!
