Adding program managers for the Education & Startup community programs

Why is this change being made?

Currently we do not have program managers listed for the Education or Startup community programs - this is a potential issue as it means team members may not be able to identify a DRI for these programs.

I requested clarification in #community-programs and @akarsten1 replied that he could be listed as the program managers temporarily - so this MR is actioning that!

Slack conversation copy per the checklist:

@tom_mcatee: I was reviewing some of the community program handbook pages and I noticed that we're missing two Program Owners (for Education & Startups) on one of the pages. Are those roles vacant, or can we update this? :meow-think:

@Alex Karsten: We can update those to me for now!
