Fix opensearch theme version

Originally, in Advanced setting, there is a setting let you set theme version from `v7` to `v8(beta)`
implying version that do not exist yet.

Change the version label to `v1` as default theme and remove the beta version.
Hide `theme:version` UI from Advanced Setting since we have only one theme avaialble now.

When producing distributable bundles the default shifts to `*` so that the distributable bundles will include all themes, preventing the bundles from needing to be rebuilt when users change the active theme in OpenSearch Dashboards's advanced settings.
 
 To customize the themes that are built for development you can specify the `OSD_OPTIMIZER_THEMES` environment variable to one or more theme tags, or use `*` to build styles for all themes. Unfortunately building more than one theme significantly impacts build performance, so try to be strategic about which themes you build.
