Wrong render in changelog file that use CRLF

[danygold]

Describe the bug
Plugin currently fully supports only CHANGELOG.md files that use LF line separator. Using a different line separator can leads wrong markdown/html/plain text render.
PR #177 resolve a regression introduced in 2.1.0 version of plugin, and take stability to the patchchangelog task, but there are some other bugs that are present.

Main bug are:

• HTML render generate wrong link
• HTML render generate an HTML that contains unnedeed new line
• Plain text render generate a wrong formatting (E.g. duplicated empty line)
• Markdown render add an unnecessary newline between links

To Reproduce
Please check this test repository. I added some unit test, and the result can be view at this link

Expected behavior
Output of the plugin is consistent with all line separator.

Environment:

• OS: Windows
• Gradle Changelog Plugin Version 2.1.1
• Gradle Version 8.1.1

Additional context
This issue isn't a regression of a recent version of plugin (2.0.0 is the last version that i tested for a possible regression)
