go: Bump ports for go124 update

sysutils/snmp_exporter: update to 0.28.0

Assign maintainership to submitter.

changes since the previous port version (0.20.0) are too numerous to
list here but can be found at the GitHub releases page:

  https://github.com/prometheus/snmp_exporter/releases

this release introduces a breaking change in the configuration file
format.  to address this:

- add a new pkg-message that explains the situation on upgrade.

- add an UPDATING entry to warn ports users about the change.

- add a new port called 'sysutils/snmp_exporter20' containing the old
  0.20.0 version; users who don't want to immediately update their
  configuration can instead switch to this new port to continue using
  the old version.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.
