Add CI for this repository to build the DSUs and publish them to the dapp market

Since the glass wallet workspace is already prepared to load the DSU explorer from the market, all that is left now it to add CI to this repository to it will properly build and publish the necessary dapps (in this case the dossier wallet and ssapp)

The closest CI to what this one will be is the Wallet, so base yourself on that.

make use for dsu-utils 'startServerAndRun' script if needed (or just got with npm run server & / sleep).

There is an undocumented behaviour that OpenDSU creates enclaves to store the SeedSSIs on the VAULT_DOMAIN env variable (defaults to vault). Please make sure you use the proper vault domain
