Show browsable code with SWH iframe

[moranegg]

Problem

Preview of software is not browsable even when SWHID is available

Solution

• When SWHID is available, show iframe
• Under the possibility to download file, show browsable source code using the SWH iframe.

example:

<iframe style="width: 100%; height: 500px; border: 1px solid rgba(0, 0, 0, 0.125);"
        src="https://webapp.staging.swh.network/browse/embed/swh:1:dir:40614bb9479925c9ca7fd22f02e4d9a34fa73026;origin=https://sandbox.zenodo.org/d5246ebd-04a9-49b2-b8dc-f0fd0aebfcbd;visit=swh:1:snp:9e7f4e90dc0da1120f1c6df5c9e5b6f0e3cbd836;anchor=swh:1:rel:016efb54a4fdfe6a7b5f89276967dfac1d5e8018/">
</iframe>

Alternatives

It's a very nice to have.

Additional context

It will be so cool to browse the code on the InvenioRDM record.
