fix(persister): requests -> request in HarEntry declaration

[ROpdebee]

Description

Fix typo in HarEntry type declaration. In reality, the property is called request but the declaration uses requests instead.

Motivation and Context

See above.

In addition to this fix, the declaration is also lacking the _recordingName and creator properties for HarLog instances, but I'm not sure how to best handle these as they are added by the base persister implementation, so it could be possible that a custom persister omits these properties. Perhaps the HarLog declaration should be made generic to handle this? Happy to add it to this PR in case that's desired.
