Great work please update the version in the package.json file, update the changelog and add the deployment tag so we deploy versiojn 0.5.0

@josemarinas done!

still, I think the way to go should be:

• merge this PR to make chore: added zksync sepolia support #84 succeed
• then merge chore: added zksync sepolia support #84
• and open a PR from develop to main with the config-release tag to release this new version

otherwise, we will have a release version that is not on the main branch
