BUILD: Incorrect filenames on pypi
### 

- [X] I have read the [installation guide](https://pandas.pydata.org/pandas-docs/stable/getting_started/install.html#installing-pandas).


### Platform

Linux-4.15.0-144-generic-x86_64-with-glibc2.27

### Installation Method

pip install

### pandas Version

latest

### Python Version

3.8

### Installation Logs

Files on  https://pypi.org/project/pandas/#files appear to have a duplicated platform tag e.g.
```pandas-1.3.2-cp38-cp38-manylinux_2_17_x86_64.manylinux2014_x86_64.whl```
instead of
```pandas-1.3.2-cp38-cp38-manylinux_2_17_x86_64.whl```

So pip installs are not able to match and will attempt to build from source.
