## Summary
This PR started out as an attempt to resolve
https://github.com/elastic/kibana/issues/166559; which it does, the
appropriate colours for the message prompt displayed when an edit
attempt on read only content is made in the code editor for both dark
and light mode are now set;
### Light mode

#### Noteworthy**
- See https://code.visualstudio.com/api/references/theme-color for more
clarification on the style definitions added to this PR
- There's also been accommodation made for consumers of the code editor
to provide their own custom message through the prop `readOnlyMessage`.
- That been said it's worth pointing out that this PR updates
react-monaco-editor and monaco-editor packages to their latest version,
primarily because the functionality that provides support to provide
customization for the providing a color scheme that would support in our
use case for setting colors for dark mode and light mode appropriately,
shipped in version 0.40.0 of monaco editor, also for react-monaco-editor
prior to it's current latest the pinned version of monaco editor was
0.38.0.
- Monaco-yaml is also updated in the PR, matching the change in
expectation of the underlying monaco-editor api.
~- Updates to the packages referenced above, in turn caused the
installed version of prettier to be updated to the latest minor version
2.8.8. This change caused some lint changes to the project files where
parentheses were added to types with Index Access on another type
created using the typeof operator (more context
[here](https://github.com/prettier/prettier/issues/14990)), for this
reason I've opted to lockdown prettier version, so that this PR only
contains the changes required for updating the code editor. A subsequent
PR will be created to revert the package lockdown so that PR contains
only the lint changes that will occur.~

### Risk Matrix
Delete this section if it is not applicable to this PR.
Before closing this PR, invite QA, stakeholders, and other developers to
identify risks that should be tested prior to the change/feature
release.
When forming the risk matrix, consider some of the following examples
and how they may potentially impact the change:
| Risk | Probability | Severity | Mitigation/Notes |
|---------------------------|-------------|----------|-------------------------|
| Multiple Spaces—unexpected behavior in non-default Kibana Space.
| Low | High | Integration tests will verify that all features are still
supported in non-default Kibana Space and when user switches between
spaces. |
| Multiple nodes—Elasticsearch polling might have race conditions
when multiple Kibana nodes are polling for the same tasks. | High | Low
| Tasks are idempotent, so executing them multiple times will not result
in logical error, but will degrade performance. To test for this case we
add plenty of unit tests around this logic and document manual testing
procedure. |
| Code should gracefully handle cases when feature X or plugin Y are
disabled. | Medium | High | Unit tests will verify that any feature flag
or plugin combination still results in our service operational. |
| [See more potential risk
examples](https://github.com/elastic/kibana/blob/main/RISK_MATRIX.mdx) |
