feat: Fix any missing spaces around Boolean operators

[claremacrae]

Description

Motivation and Context

Make the parsing of Boolean filters a bit more forgiving, by adding any missing spaces around Boolean operators
This is easy to do now that we have the simplified instruction line.

Note: I will update the documentation in a separate PR.

Now

For example this line:

(path includes a)AND NOT(path includes b)

Becomes this:

(f1)AND NOT(f2)

Which Tasks now converts to this, which just works:

(f1) AND NOT (f2)

In Tasks 6.2.0 and earlier

Previously the above input line gave this error:

Tasks query: malformed boolean query -- Unexpected character: A.
A closing parenthesis should be followed by another closing parenthesis or whitespace
(check the documentation for guidelines)

How has this been tested?

• Automated tests
• Exploratory testing
