Copy updates (#699)

* fix: update search page copy

To improve readability:
- update the page title and H1 to "Search MoJ data"
- update the details component summary text to "Search tips"
- update the link text within the details component to "More advanced search options"

* Remove comments from translation file

These are not particularly helpful. If we need them for disambiguation,
then it is better to use `pgettext`, which lets us add a context.
