Change expected newline char when parsing crypto test baseline file.

[mdaigle]

Description

CoreCryptoTests fail when run on linux because line endings are normalized to LF when the repo is checked out. The tests are otherwise still applicable to linux and can pass when the "baseline" files containing the keypairs are properly parsed.

This PR:

• Adjusts keypair files to use LF in place of CRLF.
  • This doesn't show in the diff, unfortunately.
• Adjust file parsing to look for LF.

Pull Request Overview

This PR fixes CoreCryptoTests that were failing on Linux due to line ending differences. The tests parse baseline files containing keypairs, which use CRLF on Windows but are normalized to LF on Linux checkout.

• Updated regex pattern to look for LF (\n) instead of CRLF (\r) when parsing parameter data
• Adjusted baseline keypair files to use LF line endings (not visible in diff)

I still see failures in Windows jobs in the linked build, is that expected?

I guess the correct build is https://sqlclientdrivers.visualstudio.com/ADO.Net/_build/results?buildId=127290&view=results
