Update rules to follow the Sigma state specification
...
The [Sigma specification's status component](https://github.com/Neo23x0/sigma/wiki/Specification#status-optional ) states the following:
> Declares the status of the rule:
> - stable: the rule is considered as stable and may be used in production systems or dashboards.
> - test: an almost stable rule that possibly could require some fine tuning.
> - experimental: an experimental rule that could lead to false results or be noisy, but could also identify interesting events.
However the Sigma Rx YAML specification states the following:
> ```yaml
> status:
> type: //any
> of:
> - type: //str
> value: stable
> - type: //str
> value: testing
> - type: //str
> value: experimental
> ```
The specification confuses the `test` and `testing` state. This commit changes the `test` state into the `testing` state which is already used in the code-base:
- [`sigma/sigma-schema.rx.yml`](https://github.com/Neo23x0/sigma/blob/a805d18bbae60d3e4f291c8a18304104ed2e71c7/sigma-schema.rx.yml#L49 )
- [`sigma/tools/sigma/filter.py`](https://github.com/Neo23x0/sigma/blob/f3c60a63099f80296c8750aaba667e98ac71a4f7/tools/sigma/filter.py#L26 )
- [`sigma/tools/sigmac`](https://github.com/Neo23x0/sigma/blob/4e42bebb3480720966a59528cd8482c6271e603c/tools/sigmac#L98 )
Although not modifyable through a PR, the specification should furthermore be updated to use the `testing` state.
