docs: change example for apache-config (#2091)

Closes #2090 

* change example for apache-config

This is a PR for issue #2090

Instead of using `mod_rewrite`, it may be possible to use `FallbackResource` (see https://httpd.apache.org/docs/2.4/mod/mod_dir.html#fallbackresource).  
That would be more concise and would not depend on `mod_rewrite`.

Disclaimer: I just started with vue and am not an expert with apache :)

* revert to original example, add fyi-notice
