False-negative on JSON import

[tpluscode]

This could potentially affect other non-script imports?

I have in my code this import:

import mockObjects from './mock-data.json' assert { type: 'json' }

The plugin complains and when "fixed", it changes that line into

import mockObjects from './mock-data.json.js' assert { type: 'json' }

I think that rule should only apply to some pattern, like/.+(t|j)s(x)?/ by default. Possibly configurable.

Here's how I modified the rule to only apply to js(x) and ts(x) imported modules
