docs: update release notes for NoOp HTLCs
What changed, and why it matters
This commit only updates the release notes documentation. It adds a description of a previously merged feature called NoOp HTLCs, which allows sending placeholder payment contracts that don't move money. There is no code change, no bug fix, and no security-related content in the commit itself.
No security action needed. This is a documentation-only release-notes update. Reviewers may optionally verify that the described feature's implementation (PR #9871) was itself reviewed for security, but that is outside the scope of this commit.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff adds seven lines to docs/release-notes/release-notes-0.20.0.md describing PR #9871 (NoOp HTLCs). It explains that NoOp HTLCs can be sent to a remote peer without altering channel balances, are restricted to custom channels with a specific TLV flag, and let metadata-carrying HTLCs be reflected on the commitment transaction without transferring millisatoshis. The change is purely documentation.

# New Features
+- Added [NoOp HTLCs](https://github.com/lightningnetwork/lnd/pull/9871). This
+allows sending HTLCs to the remote party without shifting the balances of the
+channel. This is currently only possible to use with custom channels, and only
+when the appropriate TLV flag is set. This allows for HTLCs carrying metadata to
+reflect their state on the channel commitment without having to send or receive
+a certain amount of msats.

## Functional Enhancements
* RPCs `walletrpc.EstimateFee` and `walletrpc.FundPsbt` now
