DS-1472 Capitalization of Workflow in Submissions & Workflow

This is a title, which means it should be capitalized.

This was committed to dspace-3_x (PR#184), however not to master. It is listed as fixed in 4_x on the release notes.

Update documentation for 4.0-rc1
[maven-release-plugin] prepare release dspace-4.0-rc1
[maven-release-plugin] prepare for next development iteration
Fix accidental duplication of access step config
Fix config default value / docs: directory not URL

Ensure that the suggested default setting for the "failed package directory" is
actually a directory (as expected by the code that uses this setting) and
matches the value of this setting in the official DSpace documentation. Both
for v1 and v2 of the SWORD server.
DS-1754 Use canonical not absolute path

Using the canonical path when determining the location of the undo information
leads to consistent behaviour when using "." as the source vs using eg an
absolute path. This also adds the name of the directory to the error message in
case the directory cannot be created, to help with troubleshooting.
