Improve Product Getting Started Page by listing logos as well as names of SDKs

[PeloWriter]

The current page https://docs.sentry.io/product/performance/getting-started/ can be hard to quickly scan. It would be improved by adding logos.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Accepted, I will leave it alone ... forever!
