UI/UX Canvas 'Add' and 'Manage library' tool tips and menu names inconsistent

Overview

There are several menu options with associated tooltips and resulting menu items within the Canvas UI at top-left:

1. Add
2. Layers
3. Manage library
4. Pages
5. Templates

Of the final 4, only 'Manage library' includes a verb, whilst the others do not.

I appreciate why this is 'Manage library' because the 'Add' menu goes to a menu called 'Library' rather than a menu with the title 'Add', but this is confusing and possibly jarring ("I hit Add and I end up on a Library page").

And I know naming things is hard ;)

Setup:

git clone git@git.drupal.org:project/drupal_cms.git --branch 2.x
cd drupal_cms
ddev launch

Edit homepage and see menu (compressed or extended) top-left.

Proposed resolution

Leave the '+' tooltip as 'Add', but change the menu title to 'Add' so they match.
Change 'Manage library' tooltip and menu title to 'Library'.

User interface changes

As above.
