Support juvix format with no argument to format a project (#2208)
When `juvix format` is invoked from some directory within a juvix
project then the formatter is run on all the files contained in the
project.

If `juvix format` is run from some directory outside of a Juvix project
then an error is reported. The user gets the same error as they would
get if
`juvix format` was run with a directory argument that is not within a
Juvix project.

* Closes https://github.com/anoma/juvix/issues/2087
