I had a look at my previous PR when I imported jules-shared to the UM. /pull/138

I've identified another place which needs a tweak.

James Bruten (@james-bruten-mo) I didn't make this comment particularly clear what needed changing:
The "Important" box in https://metoffice.github.io/simulation-systems/Development/TestSuites/jules.html reads:

For jules-shared changes, when LFRic testing, the changes need to be manually synced to the LFRic location. When UM testing, this is not required as jules-shared is imported from the JULES branch.

which will need updating as it no longer needs manual syncing.

Most of the shared metadata stuff is described in the wiki which I need to migrate to GitHub. The links to this therefore are currently broken.

[Maggie (maggiehendry)]

Please see the other comment regarding another place that needs tweaking which mentions the need to manually sync jules-shared.

[James Bruten (james-bruten-mo)]

Thanks Maggie, made those further tweaks. I don't think the important box in the JULES testing page is adding much anymore, so I've removed that. Instead I've added a new section to the macros page, advising that a macro in um-atmos and jules-lsm will be required for jules-shared changes. It's slightly duplicating some of the lines in the metadata-guidance section, but worth highlighting under macros.

Thanks for making these changes. I think it all looks good now. 😄.

Changes look sensible and render correctly. PR approved and will be committed once other changes are ready to go.
