`read_credentials()` loads incorrectly trailing lines as the value (incl. embedded newlines)

• [ ] a suggested code or documentation change, improvement to the code, or feature request

~/.aws/credentials:
[default]
aws_access_key_id = ABC
aws_secret_access_key = DEF
# foo = bar

Expected: key=ABC, secret=DEF Actual:

> str(aws.signature::locate_credentials())
List of 4
 $ key          : chr "ABC"
 $ secret       : chr "DEF\n# foo = bar"
 $ session_token: NULL
 $ region       : chr "us-east-1"

Note the embedded newline in the secret and the trailing content causing the authentication to fail.
