Update uv schema to include "all" as a valid option for default-groups

[neggles]

Update uv's configuration schema/sub-schema to allow setting the bare string "all" for default-groups; this is permitted as of v0.6.8 (see changelog here and pull request here)

I went with changing this to an anyOf and adding the specific all string match as one of the valid options since that seems more in line with the rest of the schema's style, but just changing line 90 to "type": ["array", "string", "null"], would work as well. I don't think it's likely that this field will get any other string options in the future, though, so probably constraining to the specific value is the way to go?

Agreed!.

Sidenote, I'm pretty sure this schema is autogenerated so I'm not sure if this will be overwritten at a later update.
