[platform-releng-dev] Update bookmark; Hudson shared instance (for unit

["David M Williams" <david_williams@xxxxxxxxxx>]

The Hudson instance where we run our unit
and integration tests is now accessible via 

https://hudson.eclipse.org/shared/view/Eclipse%20and%20Equinox/

This is similar to the old URL of 

https://hudson.eclipse.org/hudson/view/Eclipse%20and%20Equinox/

but now has 'shared' in the URL path
, instead of 'hudson'. 

The old instance will remain around
for a while, while (other) project migrate, but our migration is complete.
