Hide Help button in About business for AGM location change has a break while closing.

Describe the bug in the current situation
When the user starts AGM Location Change and clicks on the Help section and then when the user clicks back on Hide Help the component closes up but highlights the header.

Steps to reproduce the behavior:

1. Go to 'https://test.business.bcregistry.gov.bc.ca/BC1062080/agm-location-chg'
2. Login with BCREGA001/98900001
3. Click on Help and then click on Hide Help Button
4. The component closes but the focus on the header still remains.

The help panel closes correctly but the transition is a bit jerky.

As the fix will be to the shared ExpandableHelp component, AGM Extension help will also be fixed.

I researched this and found other people who had similar complaints about the Vuetify "expand" transition.

I tried a few different transitions (scale, scroll-y and slide-y) and ultimately decided to change this to the slide-y transition with the "hide-on-leave" option.

Note that this fix is to a shared component, so all UIs that import the latest version will see the improved behaviour.

This is now fixed, reviewed, merged into Dev and RFQA.
