docs: update examples to new helm install command format

[humb1t]

Proposed changes

Tried example with helm 3.5.2 and it does not support --name flag. So I moved name and repository to first line of commands.

Thank you very much for your contribution to the documentation! Due to the way Docusaurus versioning works, you need to make the changes in two locations:

• docs/versioned_docs/version-v{version}/path/to/file
• docs/docs/path/to/file

Without making them in both locations, the changes will most likely be lost when releasing another version. Thank you! :)
