[ADD] events: event templates doc

[ksc-odoo]

PROJECT TASK: https://www.odoo.com/web#id=3901937&cids=3&menu_id=4720&action=333&active_id=3835&model=project.task&view_type=form

This BRAND NEW PR will focus on everything the user should know about Event Templates

• new workflow
• new screenshots
• added to toctree

This PR is also adhering to some recent feedback I've received about getting too granular with explanations, so I am attempting to be more concise with the instructions presented throughout.

Also, this PR should be merged/published AFTER #8929 , because there is a lot of referenced links used in this PR, which will likely result in continued build errors until that create_events doc is published.

Alrighty, @Felicious -- this one is ready for a Peer Review whenever you get a chance. As mentioned in the initial description of this PR, there are build errors because a different PR needs to be merged/published first (and its referenced in this PR)... but other than that, it should be good to go 👍

Awesome work on this document, @ksc-odoo!

It provides a comprehensive overview of the Booth tab, which hasn't been covered in the Events documentation before. I really appreciate how you've kept the document concise by linking to relevant resources, ensuring we avoid any duplicate information across our docs.

I just had some minor rewording changes for you to consider, so after taking a look at those, feel free to move this onto the next stage of review!

Thanks for the super helpful feedback, @Felicious -- just implemented all your changes, and believe this one is now ready for Final Review, @StraubCreative 👍

There's only a few comments for you below but they're all high-level and optional, for you to consider. In any case, approving for the next round, so feel free to tag SALI when you're ready, thanks!

Thanks for the helpful feedback, @StraubCreative -- I implemented all your suggestions, and believe this is now ready for Tech Review, @samueljlieber
(I'm having a consistent build error that I am hoping you can help me fix 🙏 )
