Assertion Fails on JSON field with invalid character (hyphen)

[fgrande]

I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

Asserting a field that contains an hyphen in its name result in an error.
For instance, in the associated bru file, the assert

res.body.life-span.begin: eq "1989"

result in a problem, since "life-span" is not a valid js fieldname

Trying to attach a PR that would solve the issue

.bru file to reproduce the bug

[lohxt1]

writing the expression like below should work

res.body?.['life-span']?.begin

[fgrande]

@lohxt1 I confirm it works, thanks a lot for the hint. Actually it works also as "res.body['life-span'].begin"
Anyway, wouldn't it be nice to write it in a simpler way ?
