Let style the title of Journey Diagram

[acalvo]

Is your feature request related to a problem? Please describe.
AFAIK (please correct me if I'm wrong), it's not possible to style the title in Journey Diagrams.

Describe the solution you'd like
Ability to apply custom font/color/size/etc to the Journey Diagram title, and document it in https://mermaid-js.github.io/mermaid/#/user-journey

Describe alternatives you've considered
I checked the produced SVG, but has no CSS classes. I see nothing available to give it style (without affecting other text nodes). Example:

<text y="25" font-weight="bold" font-size="4ex" x="150">My working day</text>

@jgreywolf @sidharthv96 @acalvo Could you please direct us to resources on how to style the titles of other types of diagrams? We cannot seem to find any examples of solely titles being styled for different mermaid diagrams, and wanted to use that method of styling as a base to introduce styling for journey diagrams.

@jgreywolf @sidharthv96 @acalvo We (@Shahir-47 and myself) have passed the PR at the link #6225 ; we have added theme variables for title font size and title weight and made use of the pre-existing 'titleColor' theme variable in theme-default.js in the journeyRenderer.ts file, to introduce the ability for journey diagram titles to be styled via their configuration, and created a draft pull request. Is this approach what is expected? Attached below is a screenshot for reference:
