1973586 - Add a Python linter rule to flag imports of the standard library `json` module instead of our `mozfile.json` compatibility shim

Status: ASSIGNED

(Developer Infrastructure :: Lint and Formatting, enhancement, P3)

Description

[Alex Hochheiden [:ahochheiden] [he/him]]

We can only land this once all migrations in bug 1970521 are completed.

Since it's not possible to use orjson in all cases, we'll also need to add a way to suppress this lint via pragma so that in cases where it's necessary to use the standard library json the linter won't complain.

# noqa: TID251

Or something similar to the above (I'm not sure what the standard is for noqa).

The linter output should also communicate the existence of this pragma and when to use it, since most people getting this linter error will have none of this context.

Adding the linter should be one patch, then adding the pragmas to all the imports that could not be migrated to orson should be another.
