Broken HERMES DOI in marketplace plugin metadata

[zyzzyxdonta]

Builtin HERMES plugins are identified in the marketplace metadata by their isPartOf attribute which points to HERMES' DOI. However, this DOI is not rendered as an absolute URL (https://doi.org/10.5281/zenodo.13311079), but as a relative one (10.5281/zenodo.13311079). This is incorrect as it would be interpreted as belonging to the documentation domain (https://hermes.software-metadata.pub/en/latest/10.5281/zenodo.13311079). Thus, the absolute URL for the DOI should be rendered into the page.

When fixing this issue, the hermes-marketplace client must also be adapted. Also, the current version of the markup has to be kept for a while in order to not break the client shipped in v0.9.0.

I don't think there is a way of fixing this without the client breaking. But it's not all that bad. Instead of builtin, it will simply not say anything about the location of the plugin.
