fix(pacmak): dotnet code docs loses indentation

[kaizencc]

Currently code examples in dotnet lose their indentation styles because we call trim() on each line in the code example. We want that behavior for other types of xml docs but not for code. This PR makes code a special case that calls trimRight() on each line, preserving the indentation on the left.

The only change in the snapshots is translating this example:

docs const x = 12 + 44;
const s1 = "string";
const s2 = "string \nwith new newlines"; // see https://github.com/aws/jsii/issues/2569
const s3 = `string
            with
            new lines`;

to this:

<code>int x = 12 + 44;
string s1 = "string";
string s2 = @"string
with new newlines"; // see https://github.com/aws/jsii/issues/2569
string s3 = @"string
            with
            new lines";</code>
