[TASK] Reduce RTE options for sys_news content

System news records (sys_news) contain a `content`
field, which features a richtext editor. Previously using
the default configuration, having most of the available
options enabled.

Since system news are only displayed on the login
screen and are only intended for simple information,
most of the options are not relevant. Additionally,
some of those options did not work at all, due to
the missing frontend context (see e.g. #67556).

To ease the use for administrators, a simplified
RTE configuration is now used for the `content`
field of sys_news records.

In case administrators need additional options,
this can as usual still be achieved by overriding
the corresponding TCA configuration.

Resolves: #94980
