fix(drizzle): enforce uniqueness on index names

[r1tsuu]

Fixes #8752

Previously, trying to define a config like this:

{
  type: 'text',
  name: 'someText',
  index: true,
},
{
  type: 'array',
  name: 'some',
  index: true,
  fields: [
    {
      type: 'text',
      name: 'text',
      index: true,
    },
  ],
}

Lead to the error:

Warning  We've found duplicated index name across public schema. Please rename your index in either the demonstration table or the table with the duplicated index name

Now, if we encounter duplicates, we increment the name like this:
collection_some_text_idx
collection_some_text_1_idx

Looks good. I just have one small adjustment.
