Epic name for team upskilling

Why is the team creating items for this?  Shouldn't learning be a standard part of what they do every time that they look at a new problem to solve?  This sounds like something is being done so that their burndown charts still look good and they get credit for "burning story points" for their velocity.  

Your wanting to create an Epic for this is encouraging the behavior.  Personally, I think that a Scrum Master would want to discourage this kind of practice.  It does not communicate anything being do to the Product for enhancement and management. It is communicating career development for the individual engineers.  

We got a new requirements for our product and for that our team to upskill with new technology and get ready for implications the features to the product

Then shouldn't the estimates for those features also reflect the work needed for upskilling?

...

Now, I want to create an epic and map all those stories to this epic.

Why? Why create epics and stories which divorce this work from the valuable features of the Product?

Im jus let need your suggestion on what can name such epic so that It can easily relate to above scenario or requirements

You can't do that easily. You're setting yourself up to make it hard.

Forget about the name. How can the value of that work be determined by the Product Owner? He or she ought to be able to account for the work on the Product Backlog to stakeholders, and order it in relation to other work.
