Possibly incorrect link to main page from "Templates generator"?

[yousefmoazzam]

The use of the reference :backends_content in this line:

httomo-backends/docs/source/utilities/yaml_generator.rst

Line 5 in a34bf58

:ref:`backends_content` can be generated automatically using the YAML generator tool `provided <https://github.com/DiamondLightSource/httomo/tree/main/scripts/yaml_templates_generator.py>`_ in the Github repo.

appears to be wanting to link to the YAML templates that have been generated.

However, while the text of the link is what is expected for a link to YAML templates:

it actually links to the main page, which doesn't seem like what would be intended?

The linking to the main page is likely due to the reference being put in index.rst:

httomo-backends/docs/source/index.rst

Lines 3 to 9 in a34bf58

	.. _backends_content:
	.. toctree::
	:caption: YAML Templates
	:maxdepth: 2
	backends/templates

and should instead be moved to somewhere in the templates.rst file.
