feat: Support square brackets and curly braces to surround Boolean sub-expressions

[claremacrae]

Description

Support square brackets ([...]) and curly braces ({...}) to surround Boolean sub-expressions.

Note: more improvements are coming so I am not updating the documentation yet.

Motivation and Context

To add some alternatives to (...) and "...", for when a required filter ends with either ) or ", which would otherwise be treated as part of the Boolean logic rather than the filter.

How has this been tested?

• Automated tests
• Exploratory testing

Screenshots (if appropriate)

Example new lines:

[filter by function task.description.includes('a')] AND [description includes "hello world"]
{filter by function task.description.includes('a')} AND {description includes "hello world"}
