I guess ansible-base is being set as default when installing ansible with pip

I think maybe doing reshim is overwriting ansible executable with ansible-base executable:

```
❯ pip3 install ansible -U
Collecting ansible
Downloading ansible-2.10.6.tar.gz (29.6 MB)
|████████████████████████████████| 29.6 MB 393 kB/s
Collecting ansible-base<2.11,>=2.10.5
Downloading ansible-base-2.10.5.tar.gz (5.7 MB)
|████████████████████████████████| 5.7 MB 949 kB/s
```

As you can see is installing .6 for `ansible` and .5 for `ansible-base`.

After installing, reshim and current version:
```
❯ ./ansible --version
ansible 2.10.5
config file = None
configured module search path = ['/Users/vitorjr/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /Users/vitorjr/.asdf/installs/python/3.9.1/lib/python3.9/site-packages/ansible
executable location = ./ansible
python version = 3.9.1 (default, Jan 27 2021, 17:37:54) [Clang 12.0.0 (clang-1200.0.32.28)]
```

Not sure it it's a asdf python plugin problem related, just passing the information.

Thanks for the amazing work.

best regards,

Tái hiện báo cáo bằng `pip3 install ansible -U`, sau đó chạy asdf reshim và kiểm tra tệp thực thi `./ansible` cùng phiên bản mà nó báo cáo. Theo dõi tệp thực thi mà reshim chọn; hoàn tất khi việc cài đặt ansible 2.10.6 không khiến `./ansible --version` báo cáo ansible-base 2.10.5.
