GSUP: PDP Context ID: start at 1

In OsmoHLR, PDP Contexts can have IDs <1-10>. 0 is used internally to mark a profile slot as disabled: https://gitea.osmocom.org/cellular-infrastructure/osmo-hlr/src/commit/d4b454...

HLR Test TC_gsup_ul_subscriber_data in osmo-ttcn3-hacks also makes this assumption: https://gitea.osmocom.org/ttcn3/osmo-ttcn3-hacks/src/commit/85276b94c474bb64...

However the new GSUP implementation in PyHSS started its IDs at 0. I'll send a patch to change it to start at 1 as well.

Update the documentation to reflect that 0 is not used as PDP Context ID.
