Adjust the top navigation bar

[matt-dray]

Prompts via @swyatt-SU for the top navigation bar:

1. Change initial text [title] to 'Mitigate the growth in hospital activity'
2. Change 'Context' to 'Welcome'
3. Change 'Visualisations' to 'Explore opportunities'
4. Add a new tab titled 'How much hospital activity can be avoided?'
5. Change 'Information' to 'About this tool'

Remember to also:

• update the 'About this tool' page to reference the new section names
• address Confusing use of information icon? #197

Not difficult, but perhaps some minor considerations from a user perspective (@DCEW or @Nat-Stephenson may have thoughts):

1. To an inexperienced user, does the verb 'mitigate' imply that the tool does the mitigation, rather than providing the user with evidence they can later use to help mitigate?
2. Does 'welcome' describe what the page does?
3. OK.
4. Quite a long title that could force the menu items to be collapsed and hidden behind a menu symbol.
5. As above, would like to shorten where possible, but I accept that 'About' could be mistaken to mean 'about the data' rather than 'about this tool'.

Awaiting comments/confirmation of the content before completing this task (due 1 July).

Happy to ask a small cohort of users about these changes. From conversations and CoP around content and from looking at content guidelines (NHS/GDS), I think it is really important to try and adopt the 'standalone understandable' concept. In practice, this means that the titles of our pages/sub-pages should allow a clear understanding of what is on that page.
