Fix rich with uneven refresh rate tracking

[rohitgr7]

What does this PR do?

2 fixes here:

• One when refresh_rate isn't aligned with progress total, for eg. if total is 11 and refresh_rate is 5, it doesn't end up with the correct total.
• When using val_check_interval, rich validation bar shows total as the total number of validation steps going to happen during a single epoch, rather it should only show the total for one validation loop just like tqdm

Looks good. Do we need this in a bug-fix release?
