fix: Set TektonConfig Pruner

Starting in Tekton Operator v0.58.0, TektonConfig objects must set a
value for `keep` or `keepSince` if the pruner is enabled [1].
If Shipwright bootstraps the TektonConfig object and does not set a
value for `.spec.pruner.keep` (or `.keepSince`), it risks failing to
reconcile the TektonConfig instance or worse [2].

Fixing by setting the `keep` value to match the Tekton operator
default.

Fixes #231
