rustdoc: short descriptions cause word-breaks in tables

The `.item-table` class is used to display name+description lists, e.g. the exported functions, as a table. If the names are long and the descriptions are short, then the width of the table does not expand to the whole size, but only uses a fraction. This causes a some names to break inside a word.

This change makes the table always use 100% of its parent width. The `.width-limiter` wrapper already ensures that the used width still does not become excessive.

See e.g. <https://docs.rs/mathlab/0.3.0/mathlab/fun/vec_num/index.html> or <https://docs.rs/cw-events/0.0.9/cw_events/> (random choices out of the list of the recent releases).

The problem occurs (at least) in Firefox 130, Falkon 24, and Konqueror 22. It does not occur in Chrome 126.
