Add ITRS Geneos as vendor

[jbarossitrs]

ITRS provides an Open Telemetry plugin that works with our Geneos product, see https://devdocs.itrsgroup.com/docs/geneos/data-collection/opentelemetry/current/opentelemetry.html

I'm not sure if the conversation in #2207 applies to ITRS, please let me know if there's anything more you need to know.

@jbarossitrs please make sure that you sign the CLA

[jbarossitrs]

@svrnm I'm just waiting to hear from our legal department to confirm who our CLA Manager is and then I will sign the CLA.

[jbarossitrs]

I now have internal confirmation but have encountered a problem with easyCLA so waiting for a ticket with lxf to resolve https://jira.linuxfoundation.org/plugins/servlet/desk/portal/4/SUPPORT-16896

[jbarossitrs]

@svrnm should all be resolved now I think

/fix:format

[chalin]

I was going to offer to fix the formatting and refcache, but the PR has conflicts because the Vednors page was updated since this PR was created.

@svrnm @cartermp - I think we should switch to a data-driven approach for the vendors table so that we can avoid formatting issue, either as the part of #2178 or another issue. WDYT?

[chalin]

I thought that I might not be able to update the branch, but somewhat surprisingly I was.
Rebase done and checks fixed! 😅

[cartermp]

@chalin agreed.
