[pbs-devel] [PATCH v3 proxmox-backup] fix #6185: client/docs: explicitly mention archive name restrictions

[Christian Ebner]

Mention in the docs and the api parameter description the limitations
for archive name labels. They must contain alphanumerics, hyphens and
underscores only to match the regex pattern.

Further, explicitly mention the extension in the backup source schema
specification, to clearly distinguish this from the label and be in
line with the description give in the schema for the cli command.

By setting this in the api parameter description, it will be included
in the man page for proxmox-backup-client.
