1.27.146: pytest is failing in many units because it uses hardcoded `python` or `python.exe` python executable name

### Describe the bug

Looks like many pytest units are failing because it uses hardcoded `python` or `python.exe` python executable name.

### Expected Behavior

Instead using `pyhon` or `python.exe` it should be used `sys.executable`.

### Current Behavior

Here is pytest summary output

### Reproduction Steps

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.
- `python3 -sBm build -w --no-isolation`
- because I'm calling `build` with `--no-isolation` I'm using during all processes only locally installed modules
- install .whl file in using 'installer` module
- run pytest with $PYTHONPATH pointing to sitearch and sitelib inside
- build is performed in env which is *`cut off from access to the public network`* (pytest is executed with `-m "not network"`)

### Possible Solution

Instead hardcode python executable name it should be used `sys.executable`.

### Additional Information/Context

In summary there are some pytest warnings as well.
Here is fill pytest output as attachment [python-awscli.FAIL.txt](https://github.com/aws/aws-cli/files/11652472/python-awscli.FAIL.txt)

### CLI version used

1.27.146

### Environment details (OS name and version, etc.)
