feat: Add experimental 'show/hide tree' instruction - disabled by default

[claremacrae]

Types of changes

Changes visible to users:

• New feature (prefix: feat - non-breaking change which adds functionality)
  • Issue/discussion: Support showing tasks as indented #60
• Sample vault (prefix: vault - improvements to the Tasks-Demo sample vault)

Internal changes:

• Tests (prefix: test - additions and improvements to unit tests and the smoke tests)

Description

Warning: These instructions may be removed or renamed, and are not (yet) intended for end-user use.

Add two new experimental - and undocumented instructions:

show tree
hide tree

show tree causes Tasks to render nested tasks and list items, and is off by default.

I am not sure whether hide tree is really the right vocabulary for this long-term, but it is definitely better than hide children which was the first thing I tried.

Motivation and Context

More work on:

• Support showing tasks as indented #60

This will allow me to continue making Tasks releases whilst we improve the rendering of nested lines.

How has this been tested?

• Automated tests
• Exploratory tests

Hi @ilandikov - this is just FYI... I'll need to merge it to do a release soon anyway...
