Bug 26472: Configure Elasticsearch for better alphabetic sorting

This enhancement configures the ICU collation keyword plugin used by
Elasticsearch for sorting to better handle punctuation and whitespace in sort
fields.

Details at:
https://www.elastic.co/guide/en/elasticsearch/plugins/current/analysis-icu-collation-keyword-field.html

To test:

1. Create three authority records with the following values:

150 $a Science
150 $a Science $v B
150 $a Science $v C

2. Search for your authority records with "Science" in "Heading A-Z" order

The search results will likely be in this order:

    1. Science B
    2. Science C
    3. Science

This is an unexpected order

3. Apply the patch and reindex

sudo koha-elasticsearch --rebuild -r <instancename>

4. Search for your authority records again with "Science" in "Heading A-Z"
order

Confirm your search results show in the correct order.

    1. Science
    2. Science B
    3. Science C
