Update nightly CI pipelines to 6.1 instead of 6.0 (#3076)

### Motivation:

Active development has moved to 6.1 so the Swift 6.0 nightlies no longer
deliver much value.

### Modifications:

* Deprecate 6.0 nightly CI configuration parameters
* Introduce new 6.1 nightly CI configuration parameters
* Update the matrix generation script to handle 6.1
 
### Result:

* No more nightly 6.0 CI, 6.1 nightlies are introduced.
* Configuration for 6.0 nightlies no longer has any effect.
* All repos are automatically opted-in to 6.1 nightly linux pipelines
**even if they opted out of 6.0**.
