[docs] remove pooling models from supported features

Following up a (late) discussion in #344 about removing the pooling models from the list of supported models as not all all pooling applications are supported, and we already have embedding models in that list (see comment by @maxdebayser : link)

👋 Hi! Thank you for contributing to vLLM support on Spyre.
Just a reminder: Make sure that your code passes all the linting checks, otherwise your PR won't be able to be merged. To do so, first install the linting requirements, then run format.sh and commit the changes. This can be done with uv directly:

uv sync --frozen --group lint --active --inexact

Or this can be done with pip:

uv pip compile --group lint > requirements-lint.txt
pip install -r requirements-lint.txt
bash format.sh

Now you are good to go 🚀
