4600bf73dc 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`](a805d18bba/sigma-schema.rx.yml (L49))
 - [`sigma/tools/sigma/filter.py`](f3c60a6309/tools/sigma/filter.py (L26))
 - [`sigma/tools/sigmac`](4e42bebb34/tools/sigmac (L98))

Although not modifyable through a PR, the specification should furthermore be updated to use the `testing` state.

Eliminate title collision
Fixing the problem described in HELK here: https://github.com/Cyb3rWard0g/HELK/issues/442 where when running sigmac to generate elastalert rules, this rule has a title collision with another rule in the same directory and causes elastalert to fail to start.
