indent filter uses \n always rather than following api newline_sequence

Configure the environment with newline_sequence="\r\n"
Then use the indent filter on a multi-line macro
The returned content uses \n instead of \r\n

The expanded/indented macro should be using \r\n for end of line sequence
This would appear to be relevant source code:

Environment:

• Python version: 3.8.10
• Jinja version: 3.1.4

@jmbraben are you able to test #2031 with your use case?

I'm out of office, but I'll try when I get back...if you don't hear from me, please ping me in a couple weeks...that said, that is what I would expect the changes to look like.
I'm assuming you have tried to locate any other hard coded \n sequences?
