[Pagination] nextButton won't disable after providing float 'count' props

• The issue is present in the latest
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

When passing float ‘count’ props to PaginationComponent bugs occur.

You can see our discussion with @oliviertassinari about this behavior in this link.

The ‘nextbutton’ is not disabled on the last page when count is provided with a float number.

<Pagination count={1.3} />

Expected Behavior 🤔

PaginationComponent should return a warning when count is provided with a float number.

Steps to Reproduce 🕹

PaginationComponent proptypes uses number proptype for validating. Instead, I have changed to my custom proptype which warns the developer when he/she passes a float number as a proptype. Moreover, the component gives an error when it is not provided with a number at all.

Steps:

1. Change PaginationComponent count proptype with custom proptype

Context 🔦

I used the PaginationComponent whilst dividing the totalAmount into pages, of length 30. Sometimes this division resulted in float numbers which I passed to PaginationComponent thus I had a bug with the clickable next page button on the last page.

@fayzzzm Sounds like a plan. It might be simpler to wait for #25188 to be merged. You will need to changes.
