Update golangci-lint to newer faster version

[systay]

Description

We’ve recently updated to golangci-lint v1.60.1, but it was found to be a slower release. This PR upgrades the version to v1.60.2, which offers improved performance.

Additionally, this PR enhances the git hook to ensure that golangci-lint is updated only if the installed version is older than the required version. This prevents unnecessary downgrades and ensures that the tool is always up-to-date with the specified or newer version.
