Consider saying more about how office hours work / give examples in order to make people feel less intimidated about joining

This came from a discussion on Discourse https://discourse.llvm.org/t/office-hours-round-table-notes/82839/3?u=asb

It sounds like there's one problem of people not being aware of office hours, but I also wonder if people are intimidated about joining. If this is indeed a problem, I’d wondered about some kind “what you can expect from office hours” that reflects that different hosts might handle them in different ways but gives a little more colour beyond what is on the website already. Maybe even a "how I used office hours (and other LLVM resources) to get involved in LLVM" might be an interesting blog to arrange we could link to.

Start with the linked Discourse discussion and the office-hours material already on the LLVM website. Identify what newcomers currently lack, then propose examples or a “what to expect” guide, optionally alongside a blog or personal-experience resource. Done means the content scope is agreed and the updated guidance or linked resource is published.
