Fix for SideNav not collapsing when toggling the menu button

The `expanded` prop of the `SideNav` component was incorrectly set
as an object instead of a boolean, preventing the nav from being
collapsed. Fix the state update so it's providing a boolean as
expected.

Support specifying git revision on import resources

Add an optional input for git revision on the import resources page.
If blank the PipelineResource will automatically detect the default
branch.

Remove helper text below inputs and move content to TooltipIcon on
the label instead for a cleaner UI.

Remove Secrets and ServiceAccounts pages

Remove the Secrets and ServiceAccounts pages from the Dashboard UI,
along with the associated Create Secret / Patch ServiceAccount
functionality.

These pages provide incomplete functionality, have little to no
benefit versus using `kubectl` or other tools to manage `Secrets`,
and incur a significant overhead in terms of code maintenance since
they have to be handled differently (e.g. sanitisation of secrets
in backend).

Also remove the RBAC rules giving the Dashboard access to get/list/...
Secrets in all namespaces. This should make the Dashboard's default
permissions a lot more palatable for many users who were reluctant
to give it access to this sensitive information.

Update empty state strings for consistency and accuracy

Update the strings displayed on empty tables to be more consistent
across resource types and also to be more accurate.

Since we've added label filtering support the 'no resources found'
message has been a bit misleading, it should really be 'no matching
resources found'.

This is even more obvious with the recent addition of status filtering
on the TaskRuns and PipelineRuns lists.

Update the strings used for all namespaces, cluster resources, and
selected namespace empty states.

Suppress fetch-mock warning on fallback

By default, `fetch-mock` will output a warning when a request
is handled by one of its fallback mechanisms, e.g. `.catch()`

In our use this provides very little benefit and adds a lot of
noise to the unit test logs. Disable the warning in the test setup.

Fix key prop warning on LogFormat component

The LogFormat component is emitting a warning in dev mode
(including the tests) due to a missing `key` prop in the
`parse` function.

Add the missing `key` prop on the `<br />` element.
