feature idea: alternative heading text value for SEO reasons

[nikolastanin]

H2 added in content(or any other heading) appears as is in the content table list item, but sometimes I want to use a shorter version for SEO reasons...

actual h2 :
<h2 id="text"> iPhone 15 Pro : Specs and Features Reviewed</h2>

output:
<li><a href="#text"> iPhone 15 Pro : Specs and Features Reviewed</a></li>

I would like to have something like this:
actual h2 :
<h2 id="text" data-alternative-text="iPhone 15 Pro"> iPhone 15 Pro : Specs and Features Reviewed</h2>
output:
<li><a href="#text"> iPhone 15 Pro</a></li>

So if specified we use the data-alternative-text="" value instead. If not specified just carry on as usual.

Hope this seems like a reasonable idea :) Cheers!

actually while looking more deeply in the code i found out title="xxxxx" can be used.
