Correctly load the index.json for docs with one language

[zoglo]

This fixes an issue with the search not working for two docs due to index.json not being resolved correctly.

Seaching within the documentation of Notification Center Pro works due to having de and en:

• https://extensions.terminal42.ch/docs/notification-center-pro/en/

The search for Notification Center and Changelanguage does not work because the documentation only exists in english right now:

• https://extensions.terminal42.ch/docs/notification-center/en/
• https://extensions.terminal42.ch/docs/changelanguage/en/

Thanks for checking on this! ❤️
We've discussed with @aschempp and we actually don't want to remove the /en/ prefix because maybe at some point someone contributes another language and then all the existing links would be broken which does not make a lot of sense to us.

@Toflar

If that's the case, we should just make use of the search and fix it here:

extensions-docs/page/layouts/partials/search.html

Lines 10 to 14 in e8ee64f

	{{ if .Site.IsMultiLingual }}
	var baseurl = "{{.Site.BaseURL}}{{.Site.LanguagePrefix}}";
	{{ else }}
	var baseurl = "{{.Site.BaseURL}}";
	{{ end }}

Just using:

var baseurl = "{{.Site.BaseURL}}{{.Site.LanguagePrefix}}";

would work.

Changed it so it only affects the search

They never fixed it but in your case since you never want to remove the language flag, this should always work.
I'm too lazy to open an account and throw in my solution after 5 years.
