Block all Dependabot updates for jupyter-book

[Copilot]

The current ignore rule only blocks major version updates via update-types: ["version-update:semver-major"], but Dependabot still creates PRs for constraint updates (e.g., PR #43 changing < 2 to < 3).

Changes

• Removed update-types field from jupyter-book ignore rule in .github/dependabot.yml

When update-types is omitted, Dependabot ignores all updates for that dependency:

ignore:
  - dependency-name: "jupyter-book"
    # No update-types = ignore everything

This prevents any PRs from Dependabot for jupyter-book, maintaining the < 2 constraint required by doc/requirements.txt (see issue #12).

Original prompt

Problem

The current .github/dependabot.yml configuration is not preventing Dependabot from creating PRs to update jupyter-book. Despite having an ignore rule with update-types: ["version-update:semver-major"], Dependabot still created PR #43 to update the version constraint from < 2 to < 3.

Solution

Update .github/dependabot.yml to ignore all updates for jupyter-book by removing the update-types field from the ignore configuration.

Changes Required

In .github/dependabot.yml, change:

ignore:
  # See doc/requirements.txt for why
  - dependency-name: "jupyter-book"
    update-types: ["version-update:semver-major"]

To:

ignore:
  # Prevent any updates to jupyter-book (see doc/requirements.txt for why)
  - dependency-name: "jupyter-book"

When update-types is not specified, Dependabot ignores all updates for that dependency, which is the desired behavior given the constraint in doc/requirements.txt where we need to keep jupyter-book < 2.

Context

• doc/requirements.txt has jupyter-book < 2 to keep it at version 1.x
• This is required due to issue Can't push to pypi because of direct dependency in pyproject.toml #12
• The current ignore configuration only blocks major version updates but doesn't prevent constraint updates
• By removing update-types, we block all updates completely

This issue has nothing to do with #12, but the changes here are still relevant to prevent things like #43.
