Bump webpack-dev-server and @angular-devkit/build-angular

[dependabot]

Bumps webpack-dev-server to 5.2.6 and updates ancestor dependency @angular-devkit/build-angular. These dependencies need to be updated together.

Updates webpack-dev-server from 5.2.5 to 5.2.6

Release notes

Sourced from webpack-dev-server's releases.

v5.2.6

Patch Changes

• fix: allow undefined as the Server constructor options argument again (by @​bjohansebas in #5695)

  Restores accepting undefined (defaulting it to {}) for the options argument, so passing a webpack config's optional devServer field type-checks and works as before.

• Protect the built-in state-changing routes (/webpack-dev-server/invalidate and /webpack-dev-server/open-editor) against cross-site request forgery. Requests are now checked with Sec-Fetch-Site (falling back to an Origin/Host comparison when it is absent), so a cross-site page can no longer trigger a rebuild or open a file in the editor. Same-origin requests, user-initiated navigations, and non-browser clients (e.g. curl) are unaffected. (by @​bjohansebas in #5698)

• Handle malformed Host and Origin header values gracefully when validating requests. (by @​bjohansebas in #5699)
