add a few enhancements to the create-pr script for releases (#642)

related to
- https://github.com/nushell/nushell.github.io/pull/1114

i had to use `create-pr` to open
https://github.com/nushell/nushell.github.io/pull/1114 and i thought the
script could be improved in a few ways
- the template had a hardcoded `.0` path version in the semver, this PR
removes is so that the CLI argument can be a full semver, e.g. `0.87.0`
- switch from `explore` to `$env.EDITOR` to preview the completed
template: because it's valid markdown, it looks better in an editor
- fetch the website repo with HTTP and push with SSH: this allows to not
enter the password of an SSH key in the clone step
