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

#1456)

This reverts commit 48aceb1.

This issue was fixed upstream in git-validate with the release of
version 2.2.4. AEgir 15.0.1 uses that fixed release. As we use
version ranges for dependencies, it is automatically fixed now.
Hence reverting the original commit.

-* 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.
