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.
