update SOM sass (#204294)

fix #202769

part of #199715

## Summary

Address changes required for introducing the Borealis theme to code
owned by @elastic-kibana-core.

## Notes
No visual changes were required
- switch `$euiColorSuccessText` to `$euiColorTextSuccess` and
`euiColorDangerText` to `euiColorTextDanger` in Saved Objects management
`.scss`.
- comment on status color map

## How to test
Start ES and KIB as:

`yarn es snapshot --license trial`
`KBN_OPTIMIZER_THEMES=experimental yarn start --no-base-path`

Add the following to `kibana.dev.yml`
`uiSettings.experimental.themeSwitcherEnabled: true`
`uiSettings.overrides.theme:name: borealis`

Alternatively, switch themes in Advanced Settings:

Stack Management > Advance Setting and change the theme to Borealis.
Import saved objects in Saved Objects Management
Verify the text color used for the successfully imported saved objects.
