Fix github readme toggleMenu #1476

Hi, I tried making a PR but failed so here we are :)

In the README.md on line 243 we see menuToggle - if true clicking second time on expanded menu item will collapse it, default false., but according to your SAAS Documentation menuToggle: true # CE # if true clicking second time on expanded menu item will collapse it.

When I tried to check it out it really seemed to be enabled by default (or maybe there is another feature I don't know about), so it should be fixed in the readme too :)

PS. Over the last 2-3 days I had to search for a nice template to generate docs from OAS yaml file, yours was the best - love it out of the box <3
If there is one thing I would improve its the features we can enable/disable/specify for the documentation. It would be really cool to see a comparison on what each option really does.
Either way - thanks for making this, kudos to you all <3
