Fix `cleanupIds` option in svgo.config.js

[piotrd]

The current version of SVGO config causes an error during the build:

You are trying to configure cleanupIDs which is not part of preset-default.
Try to put it before or after, for example

plugins: [
  {
    name: 'preset-default',
  },
  'cleanupIDs'
]

This is due to the fact that cleanupIDs is misspelled. It should be cleanupIds, as per the SVGO docs.

This PR fixes the issue.

@vnbaaij since you touched the config file last, I'd love your review when possible.

Thank you. Anyone else can help? @spencer-nelson, @rachethecreator perhaps?
