Upgrade to the latest Mermaid (11.12)

[maikol-solis]

Hi!

I wanted to try the tidy-tree layout in mind maps (https://mermaid.ai/open-source/config/tidy-tree.html), but it appeared in 11.12 (https://github.com/mermaid-js/mermaid/blob/develop/packages/mermaid/CHANGELOG.md#11120).

I can't use it because the extension's version is out of date.

Thank you so much for your assistance.

I would like to update to 1.15, but cant find the possibility. It would be good to have a command to update the underlying mermaid version.
