babel.config.json language mode should be 'jsonc' #124683
Description
Babel recommends using babel.config.json since a while back. Their JSON is parsed as JSON5, which supports comments. As such babel.config.json should have the language identifier jsonc. In addition the file .babelrc.json should also be get the same language id.
See https://babeljs.io/docs/en/config-files#supported-file-extensions
The change should be done here:
vscode/extensions/json/package.json
Lines 45 to 63 in 1cce707
Note that .babelrc is still valid and should continue being identified as jsonc.
