Docs: P2P Transfer Tutorial Issues

This issue refers to the following page: https://0xmiden.github.io/miden-docs/imported/miden-client/src/get-started/p2p-public.html

**Multiple issues on P2P public transfer page:**
- Broken "Miden client documentation for clarifications" link
- Non-working "Miden faucet website" link
- Step "2. Have account C consume the note" needs clearer instruction to switch directories to account C before sync & submit transaction

The issue points to a specific documentation page (p2p-public.html). First, locate that file in the repository. Then, fix the two broken links and clarify the instruction for step 2 about switching directories. Verify the changes by building the docs locally or checking the rendered output.
