Fix malformed XML documentation in PersistentStateAttribute

[Copilot]

Summary

Fixed malformed XML documentation in PersistentStateAttribute.RestoreBehavior property that was using incorrect <code cref="..."/> tags instead of the proper <see cref="..."/> syntax.

Problem

The XML documentation was using <code> tags with cref attributes to reference enum values:

/// Use <code cref="RestoreBehavior.SkipInitialValue"/> to skip restoring the initial value

The <code> tag is meant for code samples, not for creating references to types or members. This results in malformed documentation where the cross-references won't work properly in generated documentation or IDE IntelliSense.

Solution

Changed the tags to use <see cref="..."/>, which is the correct XML documentation syntax for creating references:

/// Use <see cref="RestoreBehavior.SkipInitialValue"/> to skip restoring the initial value

This change ensures that:

• Documentation tools can properly generate hyperlinks to the referenced enum values
• IDEs can provide proper navigation through IntelliSense
• The documentation is consistent with the rest of the codebase (e.g., RestoreBehavior.cs already uses <see cref="..."/>)

Changes

• Updated XML documentation for PersistentStateAttribute.RestoreBehavior property
• Changed <code cref="RestoreBehavior.SkipInitialValue"/> to <see cref="RestoreBehavior.SkipInitialValue"/>
• Changed <code cref="RestoreBehavior.SkipLastSnapshot"/> to <see cref="RestoreBehavior.SkipLastSnapshot"/>

Describe the bug

When we look in the source of PersistentStateAttribute we see that it uses <code /> tags to link to a type/value, but that is not the right syntax for XML Documentation.

Expected Behavior

The <code /> tags should be changed to <see /> tags.

/// <remarks>
/// By default it always restores the value on all situations.
-/// Use <code cref="RestoreBehavior.SkipInitialValue"/> to skip restoring the initial value
+/// Use <see cref="RestoreBehavior.SkipInitialValue"/> to skip restoring the initial value
/// when the host starts up.
-/// Use <code cref="RestoreBehavior.SkipLastSnapshot"/> to skip restoring the last value captured
+/// Use <see cref="RestoreBehavior.SkipLastSnapshot"/> to skip restoring the last value captured
/// the last time the current host was shut down.
/// </remarks>

I can submit a PR if you would like.
