[dependabot] Ignore all npm major version updates

[imnasnainaec]

All four reviewers of #4081 (2 people, 2 bots) missed an invalid configuration, which failed when it was merged into master: https://github.com/sillsdev/TheCombine/runs/59809907546

Dependabot encountered the following error when parsing your .github/dependabot.yml:
Update configs must have a unique combination of 'package-ecosystem', 'directory', and 'target-branch'. Ecosystem 'npm' has overlapping directories.

Rather than reverting, this pr has dependabot ignore all major dep updates in the frontend. Most should be handled manually anyway.
