Fullcalendar: v6.0.0-beta.1 Release

FullCalendar no longer attempts to import .css files. Instead, FullCalendar's JS is responsible for injecting its own CSS. This solves many issues with third party libraries:

• Webpack: no longer necessary to use css-loader (see example project)
• Rollup: no longer necessary to use a css-processing plugin (like postcss) (see example project)
• NextJS: no longer necessary to ignore and manually import .css files (see example project, #6674)
• Angular 14 is incompatible with FullCalendar v5 (see ticket). FullCalendar v6 restores support for Angular 14 and above, but does so via a completely different package. Please use the new FullCalendar Web Component package (@fullcalendar/web-component), which can integrate with Angular via the method described here. Also, visit the example project.
