💄 Mermaid diagrams do not follow Loopdocs color scheme

[ebouchut]

The Mermaid (sequence) diagrams do not follow the LoopDocs' color scheme.
They use accent color #526cfe instead of the primary color #18A0A0 for actors, participants, steps, box borders...
This is mkdocs-material's expected behavior but is not in line with our color scheme.

@marionbarker I suggest configuring the diagrams to use the primary color for these graphical components.

I found a way to configure this thanks to a recent mkdocs-material update.

Adding this to docs/stylesheets/extra.css would do the trick:

.mermaid {
   --md-mermaid-node-fg-color:  #18A0A0;
}

Reopening as this no longer works (due to a change in mermaid.js?).

PR #785 fixed this issue.
