add alternative name without dashes

[Haroenv]

for create-react-native-app this should be createreactnativeapp. This is because it's often easier to just write it without dashes.

To remove is:

• .
• -
• _
• @
• /

The alternative name should have a lower relevancy score than the real name to avoid react-native to score above reactnative when you search for reactnative.

This should also be done for the keywords, but in that case the concatenated version can simply be added.

Just to recap the chat we had:

• Add a new attribute, which is the name fully concatenated (without .-_@/)
• Put this attribute in searchableAttributes, below the original name
• Instead of doing the optionalFacetFilter against the name, do it against this new attribute, using a concatenated form of the query
