Update apache-example for history-mode (documentation)

[doppelreim]

What problem does this feature solve?

For HTML5 History Mode, there are some example server-configurations in the documentation.

See https://github.com/vuejs/vue-router/blob/dev/docs/en/essentials/history-mode.md#apache

I think the apache-example could be simplified by using https://httpd.apache.org/docs/2.4/mod/mod_dir.html#fallbackresource instead of mod_rewrite?

What does the proposed API look like?

FallbackResource /index.html

Hey, thanks for pointing it out. I don't use Apache FallbackResource looks indeed simpler. We are open to PRs for this kind of information but I will also like to have more people review (Will probably post the link to the PR in discord or twitter). Could you please open the PR instead to open up discussion? Thanks!

When deploying in subfolders it works for me with an additional '.'
FallbackResource ./index.html
