Link connector docs in the Add Source dialog

The access review Add Source dialog listed each connector with no
path to its setup documentation. Connectors that have a published
docs page on probo.com now surface a "Documentation" link on the
card, opening the page in a new tab; connectors without a page show
nothing extra.

The link is data-driven from the connector registry: a new
DocumentationURL on the provider Registration, populated for the 12
documented providers via a single accessReviewDocsURL helper, is
surfaced as a nullable documentationUrl on ConnectorProviderInfo and
rendered by the console only when present. This keeps the registry
the single source of truth and adds no client-side provider map.

The links resolve once the probo.com access-review docs pages are
deployed; until then they 404, so deploy the docs alongside this
change.
