Change docs-beta links to /docs

[kavilla]

A production site for documentation exist at https://opensearch.org/docs/, so we should replace all instances related to https://docs-beta.opensearch.org/.

Warning, there are multiple locations where docs-beta was inserted. For example (but not limited to):

• https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/src/core/public/doc_links/doc_links_service.ts
• https://github.com/opensearch-project/OpenSearch-Dashboards/blob/main/src/plugins/vis_type_vega/public/components/vega_help_menu.tsx#L59

Another thing to mention is that the existing production URLs are not versioned. In the future they will need to be.
