Describe the bug
patchChangelog in version 2.1.0 breaks changelog format adding unneccessary new line.

To Reproduce
Use CHANGELOG.md and run gradle patchChangelog

Expected behavior
Changelog is patched and format is not manipulated.

• Version 2.0.0 - CHANGELOG_2_0_0.md (Expected behaviour)
• Version 2.1.0 CHANGELOG_2_1_0.md (Wrong changelog format)

Environment:

• OS: Windows 11
• Gradle Changelog Plugin Version 2.1.0
• Gradle Version 8.1.1

Additional context
In previous version before 2.1.0, patchCahngelog works propertly as expected

I've investigated and seems that the issue is caused by this issue on markdown component.
In fact if i use a CHANGELOG.md that use LF line separator, issue is not present. Instad, if file use CRLF or CR, patchChangelog breaks my changelog format.

The only solution that i've found is to use the LF line separator in CHANGELOG.md.
