Closes#18531
This PR limits the range of values that can be set for `FontWeight`.
Since any value less than 1.0 or greater than 999.9 causes Zed to crash
on Windows, I’ve restricted `FontWeight` to this range.
I could apply this constraint only on Windows, but considering the
documentation at https://zed.dev/docs/configuring-zed#buffer-font-weight
indicates that `FontWeight` should be between 100 and 900, I thought it
might be a good idea to apply this restriction in the settings.
Release Notes:
- Changed `ui_font_weight` and `buffer_font_weight` settings to require
values to be between `100` and `950` (inclusive).
