Support go1.20
Hello @kirr,
with https://lab.nexedi.com/nexedi/slapos/commit/cdca92eeccf4a287dc46ce39cf9cf77c584b24ec golang1.20 was added to SlapOS and with https://lab.nexedi.com/nexedi/slapos/commit/bea93ff2dd2f9b6e099f231dea7f2139a020199e it was set to the default version. Unfortunately it uses a new URL scheme, which wasn't supported yet by nxdbom. This patch adds this new format.
Best, Levin
