Add config to sort file picker order

[GeekPro101]

At the moment, the order of files in the file picker appears to be fairly random - directories are kept together but not much else. This makes it difficult to find files in larger directories.
It would be useful if they were:

• Sorted at all, perhaps by alphabetical order
• Had a configurable sort order, perhaps under editor.file_picker, for alphabet, file size, last modified, reverse, etc.

And it's not even directories kept together 😢 - if I start a search:

File picker is already sorted there was a pr for that a long time ago and we forgot to close this.

As soon as you start typing is sorted by score ofcourse and the sorting is only used as a tiebreaker

[tennox]

But in my example the tiebreaker doesn't seem to work... (I don't see the score being different)

[pascalkuthe]

Shorter matches are preffered.

It's score -> len -> alpabetix sorting (tie breaker).

Works exactly the same as fzf

IMO the file picker should sort files by -modtime. That would make the default view useful.

It seems that #336 implements date sorting (presumably reverse?), but currently the file picker seems to be sorted by name. 😕

Found this discussion while trying to figure out what the sort order even was, because I couldn't make any sense of it. Forcing the file picker to only sort by this odd combination of timestamps guarantees a really unhelpful sort order in some of the repos I work on, since files get created and modified constantly by people who aren't me. Combined with long paths, I sometimes have to read each and every line to find what I'm looking for.

Being able to sort by name would save me considerable time.
