[PyOV] Strip minor Python version from t suffix in setupvars scripts (#32636)

### Details:
- Python version is being passed to setupvars scripts using
`-pyver=3.14t`. Then minor Python version `14t` is being compared to the
lower/upper bound, which fails the numerical comparison because there's
suddenly a `t` in the equation.

### Tickets:
 - N/A
