SIG links on Contributing/getting-started page

[NezSez]

Migrated this issue from Documentation repo:

Under Requesting Access to Groups/SIGs
"Find the group or groups you wish to join and find the sponsors"
has only a link to the generic MatterMost url.

Should this have links to actually help someone find groups/SIGS easily like:
https://wiki.rockylinux.org/team
https://wiki.rockylinux.org/special-interest-groups
https://lists.resf.org/mailman3/lists/

Or links to the actual MM SIG channels:

AltArch SIG
Containers SIG
GOV(US) SIG
HPC SIG
Kernel SIG
Plus specific packages SIG
Virtualization SIG

Or a list like:
Alternative Architectures SIG:
MatterMost Chat Channel , Maillist, Wiki

RL Maillists
Altarch is the only SIG mentioned.

No specific SIGs mentioned for the Forums site either.
