audit and update solo/local node docs for hashsphere release

[theekrystallee]

description:

the current docs for solo and local node is outdated and needs an audit and update before the upcoming hashsphere release. the existing content is incomplete, and some information is missing

this issue tracks the effort to review and update all relevant documentation pages to ensure they are accurate, complete, and aligned with the hashsphere release.

identified these pages as priority

• https://docs.hedera.com/hedera/networks/localnet
  • the solo section on the main localnet page is a placeholder with "more info coming soon..."
  • there is no dedicated documentation for solo setup, configuration, or usage. we can just link out to solo docs
• https://docs.hedera.com/hedera/tutorials/local-node

Working on this, discussing with the Solo team.

@theekrystallee can we get some feedback from the hashspheres team who is requesting this? We're working on local-node deprecation so we don't want to further lean on local-node support. If we can get their specific needs identified here we can evaluate whether there's an exception for this case but ultimately we're focusing all efforts on solo presently.

@olsentorfinn i am requesting this since our docs are outdated. i think the goal here is to stay as up to date as possible and these pages don't align. if deprecating local node is the likely outcome, not sure what's so hard about linking solo docs here but maybe i'm misunderstanding
