Ignore html-webpack-plugin which requires webpack 5

Editor assessment

The subject states both the action and its reason — html-webpack-plugin is ignored from upgrades because it requires webpack 5 — so the header communicates the pin and its justification without the diff, which is more context than most dependency chores carry. The chore(deps) classification is correct and hygiene is clean: imperative mood, no trailing period, sensible length. No body is needed because the subject already explains itself, and no footer is required. Accurate, self-sufficient, and honest: a good, publishable example.
