Microsoft365 schemas update

[tomjebo]

This adds code for new and updated schema types for the subscription releases of Office.

New stuff:
http://schemas.microsoft.com/office/drawing/2021/oembed:
DocumentFormat.OpenXml.Microsoft365.Drawing.OEmbed.OEmbedShared - CT_OEmbedShared and global aoe:oembedShared element

http://schemas.microsoft.com/office/drawing/2021/scriptlink
DocumentFormat.OpenXml.Microsoft365.Drawing.ScriptLink.ScriptLink - CT_ScriptLink and global asl:scriptLink element

http://schemas.microsoft.com/office/powerpoint/2021/06/main
DocumentFormat.OpenXml.Microsoft365.PowerPoint.Tasks.TaskHistoryDetails - CT_TaskHistoryDetails and global
p216:taskHistoryDetails

NOTE: this type and element were moved from
http://schemas.microsoft.com/office/powerpoint/2019/12/main but remain in the
DocumentFormat.OpenXml.Office2021.PowerPoint.Tasks namespace for backward
compatibility.

http://schemas.microsoft.com/office/word/2020/oembed
DocumentFormat.OpenXml.Microsoft365.Word.OEmbed.OEmbed - CT_OEmbed and global woe:oembed element

@tomjebo Don't forget to run the Generator.Linq project to generate the latest for that project (hopefully soon will be a true source gneerator but is not at the moment).

Remove the launchSettings file and can you verify that the namespace that is being removed is intentional?
