[Look & Feel] OpenSearch Dashboards should enable dark mode themes as a user-specific option

[joshuarrrr]

Currently, OpenSearch Dashboards administrators can use the Advanced Settings in Stack Management to toggle the theme between light and dark mode, with light mode set by default. As a preliminary part of https://github.com/opensearch-project/OpenSearch-Dashboards/issues/4298, we'll make dark mode the default.

Users will retain the ability to override the theme to light mode.

Edit: Dark mode will no longer be a default

I think you meant to say "we'll make dark mode the default"

@wbeckler @dagneyb Confirming - is this still planned/scoped for 2.10 or is it now targeted for 2.11?

[wbeckler]

Dark mode optional in 2.10 and default in 2.11. I think the open question is whether it's "Next" theme in 2.10

[wbeckler]

Just to clarify, I think the plan is to do "Next" theme in 2.10.

Just to clarify, I think the plan is to do "Next" theme in 2.10.

OK, I've labeled this for 2.11 and that issue for 2.10: https://github.com/opensearch-project/OpenSearch-Dashboards/issues/4677
