Is your feature request related to a problem? Please describe.

I spent a couple of hours diagnosing what appears to be some confusing API details.

The documentation for custom fields (which I mistook for meaning advanced custom fields) led to me trying to do:

{{ site.option("my_field_name") }}

to try and get the contents for an options field called my_field_name. The documentation indicated that site.meta() was deprecated and I expected that it would function like post.meta() as it had taken on it's behaviour.

Sidenote: I've now seen the documentation about how to fetch options data and other examples of how to add options data to the context.

Issue: This adds an extra step to add options to context in PHP.
Issue: site.meta() seems like a really good way to get individual ACF field data from the site.

❗I realise the solution was documented, but I didn't see it for a couple of hours, and this seems like an extra step where one shouldn't be required and there's the potential to save users from having to implement a filter when they only need to fetch a site option as a one-off.

Describe the solution you’d like

Consolidate post.meta() and site.meta() to have the same behaviour?

Option 1

1. Undeprecate(?) Site.php's meta() function?
2. Make the function auto-prefix 'options_' on the variable it fetches so that:

{{ site.meta("foobar") }}
# made equivalent to 
{{ site.option("options_foobar") }}

I realise this would be a breaking change

Describe alternatives you’ve considered

1. Provide a filter so that the user has a mechanism to amend the name of the variable fetched through site.option(). Then I could provide a list of all ACF option fields and if the variable name matched, prepend 'options_' to the variable name.
2. Add some documentation to point people to the current solution.

Additional context

Happy to help with a pull request for the docs. Not so certain that I'm comfortable enough to make any amends with the codebase.

Sorry if these feels pedantic, but I think this might catch out other developers and this might improve the developer expereince. I ❤️ Timber.
