[BUG] In README.md, we recommend to install the helm plugin from latest main, we should recommend a versioned release instead

[jessesimpson36]

Describe the issue:

Suppose a scenario where we release a 1.0.0, and we introduce a backwards incompatible change on top of that. We have not yet released yet, so the version number would still be 0.0.5, yet a breaking change occurred. If a user runs the recommended

helm plugin install https://github.com/jessesimpson36/yamldifftool.git

then they will get a backwards incompatible change.

Instead, we should find a way to install a specific version of the yamldifftool as a helm plugin. This may require introducing git tags, or github releases.
