Update Overview Community Management Guide.mdx

[NFTDreww]

I have updated the overall update overview to be more inline with the feedback given over the past few weeks, which were:

1. Reframe the intro as a wayfinding statement. Instead of opening with a content summary, open with a one- or two-sentence orientation about what community security covers and where to go. Something like: "Community Management security spans several disciplines — each with its own dedicated Framework. Use this page to find the right one."

2. Convert the best practices section into a visual index. Each of the four sections (2FA/passwords, phishing, OpSec, emergency response) already has a corresponding Framework, so we can turn them into explicit cards or a linked table with the topic, a single descriptive sentence, and the link. This keeps the content without making it feel like a dead end.

3. Cut the inline detail that lives somewhere else. For example, TOTP configuration advice, the password manager separation rule, and the DM-first policy all belong in the destination frameworks, not here. Keeping it here creates both a maintenance burden for your team and dilutes the "go there for more" message.

------------------------------------------------------------------------ Therefore I was able to make the community manage guides more of the why, what, and how/where? Explaining this information and then leading into the actual frameworks for each that ALL needs to be taken into consideration when talking about community management and it's subsequent guides/frameworks.

This included a complete reformat of this page, that I think addresses all feedback and has a cleaner flow to providing the north star for this section.
