feat: 🧑‍💻 Allow users to use jinja-templates to display first tab dynamically

[spasma]

Hey @kinghat, 👋

Thanks for creating this awesome card! I missed the feature to dynamically show the tab, as I have some dynamic content for morning, afternoon and evening.

I also saw this discussion: #70

For example I now use:

type: custom:tabbed-card
options:
  defaultTabIndex: '{% if now().hour > 17 %}2{% elif now().hour > 12 %}1{% else %}0{% endif %}'

to show different tabs by default based on the time of the day.

I've tested the old behaviour and all is still working. Please consider merging this PR.

Keep up the good work. 🎉

seems to be not working now.

It is working, but the JS in Home Assistant is cached for a long time. You cannot force to refresh it. After a while it will work.

i still want something like this so hopefully you would be willing to collaborate on it and reopen in the future.

i didn't hear anything from you in 4 months, so I changed it to a fork of your repo: https://github.com/spasma/tabbed-card-programmable

On some devices the cached js was still an issue on my HA-instance (even after core updates) as mentioned here: #105 (comment), and I got bothered with updates to your repo. so I needed a solution for that asap.

ya thats fine. im not saying its going to happen soon:tm: but i will eventually want to add dynamic templates to areas of the card. when the time comes, if youre still willing, i'd gladly accept your help.

yes, of course! no plans to add other features to it at the moment, but will keep it in sync with your changes for now. let me know if i can help anytime
