Create workflow and base image for E2E docker tests

[chatton]

Overview

In order to speed up the docker tests, we can create base image that has a scaffolded ignite app (this takes the longest)

We can then create a workflow_dispatch workflow that can be provided an EV_NODE commit as an input. This way the regular E2E tests will just need to perform the go mod edits and ignite build.

Basically this part of the dockerfile

FROM golang:1.24-alpine AS ignite-builder

# Install dependencies needed for ignite and building
RUN apk add --no-cache \
    libc6-compat \
    curl \
    bash

# Set environment variables

RUN curl -sSL https://get.ignite.com/cli@${IGNITE_VERSION}! | bash
