scheduled_task : slightly misleading `Reference` in README.md docs

Basic Info
Module Version: 3.0.0
Puppet Version: 7.4.1 (not relevant)
OS Name/Version: Ubuntu 20.04 (not relevant)**

The docs for puppetlabs/scheduled_task have some inconsistent duplication that makes it easy to misunderstand (and misuse) the scheduled_task resource type. 

There is a 'Reference' section in README: https://forge.puppet.com/modules/puppetlabs/scheduled_task/

There is a 'Reference' title on REFERENCE.md: https://forge.puppet.com/modules/puppetlabs/scheduled_task/reference

For example, here are some inconsistencies I noticed:

• In README.md, `user` has no mention of password/Run only when user is logged on, whereas that is documented in REFERENCE.md.
• In README.md, `name` shows the sub-folder format as `subfolder
  mytaskname`, whereas REFERENCE.md says `subfolder/mytaskname`

Recommendation: remove 'Reference' heading under README.md and instead just use the version in the 'Reference' tab (REFERENCE.md).

Desired Behavior: Single clear place for attribute documentation OR reliably duplicated information in both places.

Actual Behavior: Different information for the same attribute in two parts of the documentation.

No logs attached because this is a documentation issue.
