Breaking changes

Removed the following options for proposal plugins which are now handled by @babel/preset-env:
- jsonStrings
- nullishCoalescingOperator
- optionalChaining
Options for @babel/plugin-proposal-decorators have changed, so they're no longer defaulted to {legacy: true} - you'll need to change your config to decorators: {legacy: true} if you want to keep the old behaviour.

Updated Babel proposal plugin dependencies from 7.0.0 to ^7.8.3
Proposal plugins which take options can now be configured, this affects the following preset options:
- classProperties
- decorators
- pipelineOperator
Proposal plugins which require options will use the following defaults if they're enabled by a true option or all: true:
- decorators: {decoratorsBeforeExport: false}
- pipelineOperator: {proposal: 'minimal'}
This preset will validate the proposal option for @babel/plugin-proposal-pipeline-operator, as the plugin isn't currently validating the presence or value of this option.
