Support for [project] key in schema validation

[KyleMit]

When I have the following in my pyproject.toml

[project]
name = "jsonschema"

[project.urls]
Homepage = "https://github.com/python-jsonschema/jsonschema"

I get the following error message:

{"name":"jsonschema","urls":{"Homepage":"https://github.com/python-jsonschema/jsonschema"}} 
is not valid under any of the given schemas 
Even Better TOML

But this follows the python spec Declaring project metadata: the [project] table and very common examples

Can the schema validation be updated to allow for this key?

What schema is currently present in your file? (You can check that in right bottom corner next to file language type)

Initially it was set to no schema selected

But I've updatd to each of the PyProject

Actually, looks like it might be related to the json schema store file - https://json.schemastore.org/pyproject.json

And probably need to open an issue/PR there

https://github.com/SchemaStore/schemastore/blob/6d4407c3185f5d956a932fcce111f3f926c319f0/src/schemas/json/pyproject.json#L298-L310

If the schema has been set on the file (it shows up as PyProject in bottom right corner) then it's likely an issue with schema. Otherwise it could be because of #624

It looks like a deduplicate of #316. Adding version field to [project] should work.
