Unnecessary code-block escape characters in summary/report

[thgie]

When generating the summary/report, the following line leads to faulty code-blocks: https://github.com/thamara/vscode-code-annotation/blob/af81e3d02acc94050c780741e893360c0cfe709e/src/reporting.ts#L26

I might not understand the desired result, but in my case the code-block starts with the notes file name and ends before the actually annotated code.
