mermaid: refactor config to use mermaid_config.js include, only require mermaid.version in _config.yml (#909)

This PR has a bit of scope creep! This PR now:

- changes the mermaid opt-in logic to only check for the existence of a `mermaid` key instead of `mermaid != false`: this resolves the follow-up in #857
- changes the behaviour of mermaid configuration
    - instead of using `mermaid_init.html` with default settings, makes the include `mermaid_config.js`
    - the include is loaded directly into the contents of `mermaid_initialize`
    - by default, it is an empty object (i.e. `{}`), triggering the defaults
- updates docs
- adds an example to the markdown kitchen sink  

It does significantly change the interface provided in #857, and I apologize for the confusion. However, given the discussion in this PR, I think it's the best move forward!

See [Code]({{ site.baseurl }}{% link docs/ui-components/code.md %}#mermaid-diagram-code-blocks) for more information.
The minimum configuration requires the key for `version` ([from jsDelivr](https://cdn.jsdelivr.net/npm/mermaid/)) in `_config.yml`:
```yaml
# Enable or disable support for mermaid diagrams (https://mermaid-js.github.io/mermaid/)
# Supports true or false (default)
mermaid_enabled: false
mermaid:
# Version of mermaid library
# Pick an available version from https://cdn.jsdelivr.net/npm/mermaid/
version: "9.1.3"
# Configured theme of mermaid diagrams
# Pick an avaiable theme from https://mermaid-js.github.io/mermaid/#/theming
theme: "default"
# Additional configuration available matching pattern as defined in https://mermaid-js.github.io/mermaid/#/./Setup.
# For example,
# logLevel: 'fatal',
# sequence:
# diagramMarginX: 50
# actorMargin: 50
# gantt:
# barGap: 4
# topPadding: 50
```
