**Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug.

#### Code Sample, a copy-pastable example

```python
>>> import pandas as pd
>>> pd.__version__
'1.3.2'
>>> s = pd.RangeIndex(0, 5)
>>> s
RangeIndex(start=0, stop=5, step=1)
>>> import numpy as np
>>> v = np.array([False, False, True, True, True])
>>> s.where(v, 10)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/pgali/anaconda3/envs/cudf_dev/lib/python3.8/site-packages/pandas/core/indexes/base.py", line 4472, in where
    return self.putmask(~cond, other)
  File "/home/pgali/anaconda3/envs/cudf_dev/lib/python3.8/site-packages/pandas/core/indexes/base.py", line 4727, in putmask
    return type(self)._simple_new(values, name=self.name)
  File "/home/pgali/anaconda3/envs/cudf_dev/lib/python3.8/site-packages/pandas/core/indexes/range.py", line 164, in _simple_new
    assert isinstance(values, range)
AssertionError

```


#### Problem description

pandas RangeIndex is not allowing a `where` operation to be performed which was working in older versions of pandas i.e., `1.2.5`

#### Expected Output

```python
>>> import pandas as pd
>>> pd.__version__
'1.2.5'
>>> s = pd.RangeIndex(0, 5)
>>> s
RangeIndex(start=0, stop=5, step=1)
>>> import numpy as np
>>> v = np.array([False, False, True, True, True])
>>> s.where(v, 10)
Int64Index([10, 10, 2, 3, 4], dtype='int64')
```
