Add info about looking in the next section

[olivroy]

In the quarto dashboard theming section, I find it confusing where to look for to create custom.scss.

https://quarto.org/docs/dashboards/theming.html#theme-options

This link https://github.com/twbs/bootstrap/blob/main/scss/_variables.scss is very prominent, but it's not the correct place to look for.

The correct place to look for is actually https://quarto.org/docs/dashboards/theming.html#sass-variables

I am not sure how to put it, but I think that it should be more obvious.

I got confused in quarto-dev/quarto-cli#8351.

This is probably not right, maybe the correct thing would be to add {#sec-sass-variables} in https://github.com/quarto-dev/quarto-web/blob/main/docs/output-formats/_theme-variables.md but I don't know how it works with < include >

That is not correct.
The link targets the complete list of available SASS variables from Bootstrap which is correct.
The SASS variables section list the SASS variables defined/used by Quarto internally in addition to Bootstrap.

Here the change to make would be to add a cross-reference to the section (https://quarto.org/docs/dashboards/theming.html#sass-variables) and to state that there are more SASS variables available to ease customisation (in https://quarto.org/docs/dashboards/theming.html#theme-options).

Thanks @olivroy as there is indeed an improvement to be made here.

Agreed, @mcanouil and @olivroy there are definitely improvements to be made here. I'm going to close this PR in favor of this issue tracking the issues with the theming content.
