[BUG] Custom outputs don't get included in the output folder when using xlsx option

[tombisho]

Custom outputs don't seem to get included in the output folder when using the xlsx option for the format in the acro_finalise() function. This does not happen with the json format. Maybe I am doing something wrong?

Steps to reproduce the behavior:

1. Create a custom output with acro_custom_output() (in this case it was a pdf file)
2. Finalise your outputs, using the xlsx format in the acro_finalise() function
3. The target folder gets created, but the xlsx file doesn't mention the custom output, nor is the file included
4. Finalise your outputs into a different folder, using the json format in the acro_finalise() function
5. The target folder gets created, the json file mentions the custom output, and is the file included.

I would expect the xlsx option to behave the similar to the json option, in that the custom file is mentioned and included.

Version - add_conda branch (i.e. 0.1.6)

(as an aside, I wanted to use the xlsx format because 1. our TRE is Rocky Linux and can't use the .deb ACRO Viewer 2. Our Windows desktops don't allow us to install an .msi without going through a semi-painful process of asking for an exception)

@rpreen one to discuss when we meet this week, it is hard-coded into acro.record.finalise_excel() but we should revisit any implicit design assumptions / decisions

@jim-smith Has this been discussed and concluded on?

Needs further planning - quick fix possible but should this come from the viewer - and if so does it need other wait for web-app version as GitHub does not support rocky linux
