Releasing checklist:
(1) Write a changelog.
(2) Make sure to update SPDX license identifiers. For example:
# SPDX-License-Identifier: MIT
# OpenZeppelin Contracts for Cairo v0.1.0 (account/Account.cairo)to
# SPDX-License-Identifier: MIT
# OpenZeppelin Contracts for Cairo v0.2.0 (account/Account.cairo)(3) Create a release branch and add a tag to it. This branch can be useful if we need to push a hot fix on top of an existing release in the case of a bug.
git checkout -b release-0.2.0
git tag v0.2.0(4) Push the tag to the main repository, triggering the CI and release process.
git push origin v0.2.0
