feat: Add sticky table-column

This commit introduces a feature to add a sticky first column
to tables generated from the list-table directive in Sphinx.

The first column now remains fixed during horizontal
scrolling, enhancing the user experience and improving
readability, especially for long tables such as the one in
infra/inventory.rst.

The implementation uses CSS with `position: sticky`. The
CSS is added to _static/css/sticky-table-column.css and
included in the Sphinx build via conf.py.
