Fix double spacing in ClientUriBuilder generated code

[Copilot]

BinaryOperatorExpression.Write() adds spaces around operators during code generation. ClientUriBuilderDefinition was passing operators with embedded spaces (" - ", " + ", " ??= "), causing double spacing in generated output.

Changes:

• Remove spaces from operator strings in ClientUriBuilderDefinition.cs to match codebase convention

Before:

private UriBuilder UriBuilder => _uriBuilder  ??=  new UriBuilder();
if (_pathLength > 0 && PathAndQuery[_pathLength  -  1] == '/')

After:

private UriBuilder UriBuilder => _uriBuilder ??= new UriBuilder();
if (_pathLength > 0 && PathAndQuery[_pathLength - 1] == '/')
