Also fix some tests that were broken by bumping golang and dependencies
in the previous commits.
Note that in addition to changes made to satisfy the linter which do not
impact the behavior of the code, this commit also adds ReadHeaderTimeout
to all usages of http.Server to satisfy the linter (and because it
seemed like a good suggestion).
Also:
- Add CSS to login page
- Refactor login page HTML and CSS into a new package
- New custom CSP headers for the login page, because the requirements
are different from the form_post page
- Two of the linters changed their names
- Updated code and nolint comments to make all linters pass with 1.44.2
- Added a new hack/install-linter.sh script to help developers install
the expected version of the linter for local development
When the POST to the CLI's localhost callback endpoint results in a
non-2XX status code, then treat that as a failed login attempt and
automatically show the manual copy/paste UI.
This functioned fine, but did not have the intended visual appearance when it came to how the text of the auth code wrapped inside the copy button in the manual flow.
The new styling behaves correctly on at least Chrome, Firefox, and Safari on macOS.

This is a new pacakge internal/oidc/provider/formposthtml containing a number of static files embedded using the relatively recent Go "//go:embed" functionality introduced in Go 1.16 (https://blog.golang.org/go1.16).
The Javascript and CSS files are minifiied and injected to make a single self-contained HTML response. There is a special Content-Security-Policy helper to calculate hash-based script-src and style-src rules.
This new code is covered by a new integration test that exercises the JS/HTML functionality in a real browser outside of the rest of the Supervisor.
