Updates/fixes as requested by the TRC and discussed in the TSG call on 2022-07-26:

• Use Search context everywhere as it extends the Prezi context
• TermList -> TermPage in context
• Total is not in scope for how we need it in Search (inside a Term) - we need to define it to match WebAnno, which is ActivityStreams totalItems with non-negative type
• 4.2.3 - label is not a proper language map
• 4.2.2 - “track which page” -> “track which Annotation Page”
• 4.2.4 & 5.3 - fix user in examples to be a URI
