DTSTAMP docstring See also self-links to DTSTAMP

[SashankBhamidi]

The DTSTAMP and stamp attributes share a single docstring via DTSTAMP = stamp = single_utc_property(...) in src/icalendar/cal/component.py. The See also section in that docstring includes :attr:DTSTAMP``, which makes sense when rendered under stamp but produces a self-link when rendered under `DTSTAMP`.

The fix is to remove :attr:DTSTAMP`` from the See also list, since a property's own page doesn't need a link back to itself.

Hi! I’d like to work on this as my first contribution to icalendar. I’ll update the shared docstring to remove the DTSTAMP self-reference and verify the documentation build. I’ll open a PR shortly.
