Improve marketplace search to deal with spaces in search query

[hanneskuettner]

Describe the Improvement

Right now the marketplace search only works for the extension name as defined in the package name. In the app the extension names are formatted using formatTitle replacing - with a space. As such the search result for e.g. group tabs is not the same as group-tabs. The former does not list the expected extensions.

Maybe we should introduce an additional meta field, that is the formatted extension name, in the registry that is computed and set once the extension is ingested that can be searched in addition to the package name.
