Need to update 'Land Surface Component' page test with RNS release

[heidinett]

Currently in 'Configurations that use JULES' paragraph, text reads:
JULES in not used in any ACCESS-NRI-supported configuration.

When the ACCESS-NRI supported configuration of the RNS is released, we'll need to replace this line with something like: The Regional Nesting Suite (RNS) is the only ACCESS-NRI-supported configuration that uses JULES.
