fix examples links in docs

[pritidesai]

As part of a cleanup, we deduplicated tests between v1 and v1beta1 to help with flaky CI in #6908.

But, some of our docs still has a reference to examples under v1beta1. These links are not working any more. Please verify and update the doc to refer to the examples under v1 instead.

docs/tasks.md:  > - When providing value for an `object` param, one may provide values for just a subset of keys in spec's `default`, and provide values for the rest of keys at runtime ([example](../examples/v1beta1/taskruns/beta/object-param-result.yaml)).
docs/tasks.md:  > - When using object in variable replacement, users can only access its individual key ("child" member) of the object by its name i.e. `$(params.gitrepo.url)`. Using an entire object as a value is only allowed when the value is also an object like [this example](https://github.com/tektoncd/pipeline/blob/55665765e4de35b3a4fb541549ae8cdef0996641/examples/v1beta1/pipelineruns/beta/pipeline-object-param-and-result.yaml#L64-L65).
