"Append" aliases (partially) overwrite the file instead of appending to it

[ap0llo]

The "FileAppend*" aliases (FileAppendText and FileAppendLines), (partially) overwrite an existing file (writing starts at offset 0) instead of appending to it.

Expected Behavior

The content of an existing file is retained and additional text is appended to the end of the file

Current Behavior

The content of an existing file is (partially) overwritten.
When the content being appended is shorter than the existing content, the file's content is only partially replaced.

Possible Solution

When opening a file stream, use FileMode.Append instead of OpenOrCreate:

Cake.FileHelpers/src/Cake.FileHelpers/FileHelpers.cs

Line 138 in 8e78cde

using var streamWriter = CreateStreamWriter(context, file, FileMode.OpenOrCreate);
