build: vscode improvements and devcontainer support (#15395)

Add devcontainer.json to support one-click development environment. It
installs java 25, runs `gradlew eclipse`, and installs the correct
extensions. No popups or confirmations required. Only GitHub codespaces
has been tested.

Set "Standard" launch mode, the "Lightweight" mode initially started by
the default "Hybrid" setup will spew nonsensical diagnostic errors. This
is very confusing as it makes the setup appear broken, for a potentially
long time, until the "Standard" server is finished indexing (takes
~5mins on my machine).

Improve the completion speed, by reducing the amount of auto-imported
stuff (favorite static members).

Enable inlay hints for inferred variable types (`var` keyword), and
inferred parameter types (lambdas).

Remove telemetry popup for Red Hat Language Server. Local VSCode user
must still deal with 3 popups. but 3 is better than 4.

Remove ast-grep extension which errors-out if the binary isn't installed locally. User can install themselves if wanted.

Fix outdated 'java 23' in gradlew error code.
