Add tox -e cog to update README tables

[hugovk]

Also output the tables in GitHub-flavoured Markdown instead of RST, because it's README.md.

And remove the irrelevant Travis CI column, we've not used it for years and .travis.yml was deleted in 2021: python/cpython#30257

We can't use 3.14 yet because one transitive dependency is pydantic, which doesn't yet support 3.14.

They added initial support in pydantic/pydantic#11613 and have released an alpha, but we're waiting for a final release of pydantic 2.12.

This is a rather heavy dependency for an infrequent task that isn't that much of a hardship:

cog v0.16.6 ├── attrs v23.2.0 ├── fastapi v0.115.14 │ ├── pydantic v2.11.7 │ │ ├── annotated-types v0.7.0 │ │ ├── pydantic-core v2.33.2 │ │ │ └── typing-extensions v4.15.0 │ │ ├── typing-extensions v4.15.0 │ │ └── typing-inspection v0.4.1 │ │ └── typing-extensions v4.15.0 │ ├── starlette v0.46.2 │ │ └── anyio v4.10.0 │ │ ├── idna v3.10 │ │ └── sniffio v1.3.1 │ └── typing-extensions v4.15.0 ├── pydantic v2.11.7 (*) ├── pyyaml v6.0.2 ├── requests v2.32.5 │ ├── certifi v2025.8.3 │ ├── charset-normalizer v3.4.3 │ ├── idna v3.10 │ └── urllib3 v2.5.0 ├── structlog v24.4.0 ├── typing-extensions v4.15.0 └── uvicorn v0.35.0 ├── click v8.2.1 │ └── colorama v0.4.6 └── h11 v0.16.0 

I'd be fine with using GFM tables (though they're rather verbose in the source), but I don't think we need the other changes in this PR.

Good point, I've moved the cog dependency out of tools_requirements.txt, so it's only installed when running tox.

Nice improvement! Looks good to me 👍

I like cog for locality of behaviour.

Thanks @hugovk! I've heard of cog once, it's the first time I see a use of it, that's interesting :)))
