fix(mermaid): fix Mermaid integration for v9.2 release

[slorber]

Upgrading for 9.1.7 to 9.2 makes the Mermaid theme compilation fails

Unfortunately users are upgraded automatically due to using the semver range ^9.1, and it also fails at runtime for these users that should force v9.1.7 (last version that works)

See:

• fix Mermaid 9.2 falls over in Docusaurus 2.2 #8274
• 9.1.7 => 9.2: can't build with TypeScript - TS1471: Module 'mermaid' cannot be imported using this construct mermaid-js/mermaid#3747

Current PR is a draft, still unsolved 😅

---

Probably unrelated to the issue (according to my local tests) but the theme/client Mermaid apis were not compiled with the correct TS options (ie outputs CJS instead of ESM), so I'm also fixing that here.

Hi,

A temporary workaround : using Yarn, adding resolutions in package.json makes it work :

, "resolutions": { "mermaid": "9.1.7" },

Thanks @Josh-Cena and @homotechsual on #help-and-questions ;)

The issue has been fixed in Mermaid 9.2.2 and everything seems to work fine again now

Had to change a bit the types to make it work again because new official types are not exactly the same as the DefinitivelyTyped ones
