angular.json scripts support .mjs file format

[turingcs2005]

Which @angular/* package(s) are relevant/related to the feature request?

No response

Description

Currently angular.json's scripts section does not support .mjs. Some front end packages such as mermaid 10 has moved to ES modules with .mjs files

Proposed solution

Support .mjs in angular.json's scripts.

Alternatives considered

Import scripts in index.html is a workaround though not elegant.
