Description

The Management Generator was adding unwanted formatting to XML documentation tags, creating unnecessary diffs against existing code:

Before:

/// <description> /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}... . </description>
/// <description> Bars_Get. </description>

After:

/// <description>/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}...</description>
/// <description>Bars_Get</description>

Changes

• Modified XmlDocStatement constructor calls in ResourceHelpers.cs to use explicit opening/closing tags instead of tag names, preventing automatic sentence-style formatting
• Updated 4 locations: Request Path, Operation Id, Default Api Version, and Resource descriptions

Changed from:

new XmlDocStatement("description", [$"{value}"])

To:

new XmlDocStatement($"<description>", $"</description>", [$"{value}"])

This matches the existing pattern used for <list> tags in the same file.
