[DOC] Update and evaluate client and server install/config/requirements content

[knylander-grafana]

Our configuration doc is missing information about supported architecture and hardware requirements. We have install/configure content in the Get started, Configure the client to send profiles, Upgrade, Deploy on Kubernetes, and Configure the server.

Short term:

• Add a section to the both the Client and Server sections that lists supported architecture with links to various requirement and supported storage options

Long term (in a new doc issue):

• Create a "Plan your deployment" page that provides a summary of installation instructions, follow Tempo's outline as an example
• Review and restructure the client and server docs so they provide a clear path for users who want to instrument apps and set up their server.
  • Simplify the TOC topics so the navigation is clearer for people wanting to install and configure the client (instrument) and store profile data (Pyroscope set up).
