fix(@angular-devkit/schematics): replace template line endings with platform specific

Currently, when using `ng new` on Windows, users will get a number of `LF will be replaced by CRLF the next time Git touches it` warnings.

This commit, replaces the line endings in templates to be platform specific.

Closes #26764

(cherry picked from commit 7e9bbe4)
