Match multiple tags in nx-enforce-module-boundaries sourceTag

• I’d be willing to implement this feature (contributing guide)

Description

Allow rules that match multiple tags sourceTag: ['platform:frontend', 'type:core'].

Motivation

This is useful in order to be more precise when using logic similar to allowedExternalImports. Cf. #12870 E.g.:

{
  sourceTag: 'type:core',
  allowedExternalImports: []
},
{
  sourceTag: ['platform:frontend', 'type:app'],
  allowedExternalImports: ['@angular/*']
},
{
  sourceTag: ['platform:backend', 'type:app'],
  allowedExternalImports: ['@nestjs/*']
}

Perfect! I love it! I’ll give it a shot and send you a PR as soon as I can.

I would add new property e.g. sourceTagCombo, just to make it clear that those tags are combined, and not used as or. That would also help to not modify the existing functionality.

Also, sourceTag and sourceTagCombo should be mutually exclusive.
