Add Profile Name and Line Number to Config Save Error Messages

[brandonkgarner]

Adds profile name and line number to error messages during configuration save in the format: [profile_name]:##, or in the case that the profile name is not in the line (such as invalid parameter definition), grabs the value of the line: [line_value]:##

Addresses https://github.com/tilfinltd/aws-extend-switch-roles/issues/338 as I have run into the same issue multiple times.

Affects only ConfigLoadError/IniParseError that already supply a line-number from aesr-config:

• "The profile includes both role_arn and either aws_account_id or role_name."
• "The profile includes invalid role_arn parameter."
• "The profile doesn't specify an AWS account ID."
• "Invalid parameter definition"

Tested in Chrome and Firefox on MacOS 14.4.1 with the same results.
