[Reference feedback]: support in-subscription tickets filter case sensitivie but docs have wrong case

### Type of issue

Code doesn't work

### Reference command name

as per SO post https://stackoverflow.com/questions/79599403/az-cli-query-filter-for-support-tickets/79599404#79599404

All filters and queries are case sensitive, the guidance has the wrong case.

```az support in-subscription tickets --help```

shows the following text:

\> list : Lists all the support tickets for an Azure subscription. You can also filter the

\> support tickets by _Status_, _CreatedDate_, _ServiceId_, and _ProblemClassificationId_
\> using the $filter parameter. Output will be a paged result with _nextLink_, using which
\> you can retrieve the next set of support tickets.

```az support in-subscription tickets list --help```

shows the following text:

\> List support tickets created on or after a certain date and in open state for a subscription
\> az support in-subscription tickets list --filter "CreatedDate ge 2024-01-01T22:08:51Z and Status eq 'Open'"

The filter that actually works uses lowercase 'createdDate':

```az support in-subscription tickets list --filter "createdDate ge 2025-02-01"```

### Feedback

guidance and code samples should have the correct case and not extra underscores in front of property names
