Writing a word ending with "x" between brackets counts as a Checkbox

[Romsick]

Bug

Whenever you write "[max]" or any word ending with the "x" character (without the quotes) followed by a whitespace and any word/character, Boostnote interprets it as a checkbox, also inside code blocks.

The checkbox counter and the completion bar show there are uncompleted checkboxes in the note. But these aren't checkboxes and at the same time, the box to mark it as complete never appears in this cases.

To reproduce

Paste or write the following in a Markdown Note:

foo [max] bar <- IS CHECKBOX
```shell
foo [max] bar <- IS CHECKBOX
```
foo[max] bar <- IS CHECKBOX
foo[max]bar <- NOT CHECKBOX
foo [max]bar <- NOT CHECKBOX```

[min] bar <- NOT CHECKBOX
[max] tree <- IS CHECKBOX
foo [axe] tree <- NOT CHECKBOX
foo [xxx] tree <- IS CHECKBOX
foo [paranoiax] tree <- IS CHECKBOX
foo [xav] tree <- NOT CHECKBOX
foo [xxb] tree <- NOT CHECKBOX

Presuming that a checkbox can only be written in two ways
- [ ] unmarked
and
- [x] marked
then

Should be
if (trimmedLine.match(/^[\+\-\*] \[(\s|x)\] ./)) {
adding the brackets around the \s|x to make sure the or statement is only for the character in the box
