chore: add release notes for Hedera ITS max-supply patch

[rista404]

why?

This PR adds a release document for upgrading Hedera's ITS contract, specifically the Token Manager implementation.

how?

The fix is c6fda1781dfb0a00d9e74e420cca7beba9bbcda8. The release doc instructs to pull this commit, rebuild ITS and reinstall it before upgrading.

I haven't included any devnet-amplifier configuration as it was removed in #1018

Feel free to suggest any changes, I wasn't sure how to version the fork and subsequently kept 2.1.0 in the salt, with the addition of patch-1.

testing

Follow the EVM checklist and the additional registration test. Let me know if you can't find a native token with lower max-supply. I haven't included any token addresses as you can only register a single token once.

Here's a transaction that registers a canonical token with lower max supply.

Summary

This PR adds release notes for a Hedera ITS max-supply patch that fixes token registration issues for tokens with finite supply. The patch includes a specific commit that lowers approval amounts to the max supply of tokens with finite supply, preventing registration problems.

• Adds comprehensive deployment instructions and testing checklist for the patch
• Documents the fix for token registration issues with non-max supply tokens
• Includes specific testing instructions for validating the patch functionality
• Missing required --proxySalt parameters in deployment commands which are needed for consistent derived contract addresses

Confidence Score: 3/5

• This PR is relatively safe but has deployment parameter issues that need to be addressed
• Score reflects missing critical deployment parameters that could cause address derivation issues, though the overall documentation structure is sound
• The release document needs proxySalt parameters added to deployment commands
