Typo in the documentation of Episerver.Framework.Cache.ReadStrategy.Wait

Fixed typo in meta document of the enum Episerver.Framework.Cache.ReadStrategy.Wait

Documentation says:
/// <summary>Will wait for pending updates to finish</summary>
/// <remarks>
/// <para>Typically used for scenarios where there is likely that several calls are done concurrent for an item
/// that is costly to load. In that case only one will perform the actual load while others will wait.
/// When the loading is done the waiting threads will be singnalled.</para>
/// <para>This option adds a marker object to the cache to signal that data is being loaded, do not use the same
/// cache key with other API's that do not take <see cref="T:EPiServer.Framework.Cache.ReadStrategy" /> since they will return the marker object
/// if called for example during a costly database operation.</para>
/// </remarks>

There is a spelling error in the paragraph for the word "singnalled", should be "signalled", also the word "concurrent" should be "concurrently".
