Support $BROWSER envar

[kyoh86]

Describe the feature

I want the BROWSER variable to be referenced when opening the browser with a command such as aws sso login.

Use Case

We use wslview to open our browser in WSL.
However, there are many packages that easily install xdg-open as a dependency even though it is not available in WSL.
I don't want such xdg-open which does not work, to be called, so I set the BROWSER environment variable to "wslview" for various tools, but the AWS CLI ignores this.

Proposed Solution

I would like the following solution.

• Refer to the BROWSER environment variable
• Be able to specify the browser command to be used in the AWS CLI configuration file

Other Information

No response

Thanks for the sso login feature request. Have you tried setting BROWSER=wslview aws sso login? Others said in #4715 (comment) that worked.
