Normalize version_id for minor versions, e.g. 100.2 < 100.20

[c-suh]

🗒️ Summary

Note: since this uses SolrCloud, it requires a single shard to use the collapse function

Steps for normalizing version_id:

• split version_id into major and minor versions
• pad the minor version
• concatenate the major and padded minor versions
• format the string to the maximum number of decimal places for a float
• convert to a number

Examples (preformatted for easier viewing of number of digits):

100.2 becomes
100.00002
100.20 becomes
100.0002
2.40 becomes
  2.0004
