Update links to Katacoda tutorial to use the official Tekton profile

Also update link to `kubectl proxy` instructions since the previous link
is dead and breaking the PR status checks

Update PipelineRun container logic to correctly select TaskRuns with …

…conditions

The `tekton.dev/pipelineTask` label is applied to both the condition check TaskRun
and the owning TaskRun. The previous logic could in some cases incorrectly select
the condition check for display in the UI.

Update the logic to ensure a match for the `tekton.dev/pipelineTask` label is only
counted when there is no accompanying `tekton.dev/conditionCheck` label. This will
ensure the condition is only matched when the selected value appears in the
conditionCheck label, regardless of the order TaskRuns are listed in the data.

Accessibility fixes

- Ensure no duplicate table ids on the About page
- Ensure links contain text (setting `title` on the anchor tag isn't enough)

Use pipelineTask name for PipelineRun URL addressability

Instead of using the TaskRun uid + pod name in the URL to address
a specific TaskRun retry, use the more user-friendly pipeline task
name and a separate retry parameter.

This produces a more user-friendly URL, is more easily constructed
by pipeline authors, and doesn't rely as much on kubernetes-isms
(i.e. pod name).

This change is based on feedback from preview users.

Fix display of array params

Rename `WithLineBreaks` component and expand its purpose to
handle rendering of all param types, not just strings.

The newly named `Param` component will output params as YAML,
this ensure that strings (including multiline) and arrays are
formatted and displayed in a user-friendly manner.

Sort steps by timestamps in a TaskRun

Currently, all injected steps appear before the regularly defined
steps in some views. Now they are sorted by the finishedAt timestamp
in each step's status, with ties broken by the startedAt timestamp.

The current order is not always correct, since some injected steps
actually run after regular steps. This ordering also causes some steps
to be incorrectly labelled as either skipped or failed.

The new order should be better, but it will still depend on the
precision of the timestamps: seconds might not be sufficient in all
cases. There are plans in 'pipeline' to increase the precision.
