### Summary

I'm trying to optimise my builds by avoiding unnecessary downloads.
ansible-galaxy install always downloads the latest version even if the existing collection already meets the requirements. This behaviour appears to be consistent with the documentation (https://docs.ansible.com/ansible/latest/galaxy/user_guide.html#installing-an-older-version-of-a-collection), but why has it been implemented to always download ?


e.g. I have
```
# /usr/local/lib/python3.8/site-packages/ansible_collections
Collection                    Version
----------------------------- -------
amazon.aws                    3.5.0  
...
```
and requirements.yml
```
---
collections:
  - name: amazon.aws
    version: '>=1.5.0'
```
if I run ansible-galaxy install -r requirements.yml I get amazon.aws 6.1.0 installed, even though 3.5.0 already meets my 1.5.0 requirement. I would expect nothing to happen because my requirements were already met.

### Issue Type

Feature Idea

### Component Name

ansible galaxy

### Additional Information

People who like the existing behaviour could perhaps use the recently added --upgrade switch to continue to get the upgrade to the lastest version.
