I think bold is the least fitting font weight for inlay hints, which
should be subtle hints and not, well, bold.
If someone feels strongly about this, I can revert, but only if we add
the ability to change this per theme.

Release Notes:
- Themes: Renamed `scrollbar_thumb.background` to
`scrollbar.thumb.background` to be consistent with other style
properties.

This PR populates the `search.match_background` colors in the bundled
themes, using the values from the Zed1 themes.
Release Notes:
- Added theme-specific `search.match_background` colors to built-in
themes.
This PR adds serialized versions of each of the themes that currently
ship with Zed.
In a future PR we'll be looking to make these the canonical
representations of the built-in themes.
Note that we're intentionally repurposing the `theme_importer` to do
this, so that crate is a bit rough-and-ready at the moment.
Release Notes:
