[ML] move find file structure finder in Rest high Level client to its new endpoint and plugin (#67290)

Find file structure finder is now its own plugin, and separated from the ml plugin.

This commit updates the rest high level client to reflect this.

Additionally, this adjusts the internal and client object names from `FileStructure` to the more general `TextStructure`
