fix: remove notice about breaking upgrade to >= 0.30.0

This issue was fixed upstream. As we use version ranges for dependencies,
it is automatically fixed now. Hence reverting the original commit.

Revert "docs: add migration note about upgrading from < 0.30.0 (#1450)"

This reverts commit 48aceb1.

-* Git pre-push hook has been removed
-
-  **This only applies to developers that build IPFS from source, not for consumers**
-
-  This can cause problems during installation of npm dependencies, in case the repository
-  is not freshly cloned. Prior to 0.30.0 a pre-push hook has been set up to verify
-  changes before sending them to a remote repository. Due to the removal, existing
-  installations will have dead symlinks that cause `npm install` to fail.
-
-  The migration path is to remove the `pre-hook` file/symlink inside `.git/hooks` of
-  your clone.
