Index V2 does not properly handle versions of <part>.0 or <part>.###0

[Trenly]

When moving from IndexV1 to IndexV2 the code which builds up the index was heavily modified to optimize the size of the index. This has resulted in a parsing error, where versions such as 128.0 or 132.0 do not have the trailing .0 mapped into their version. When the version is more than two parts, or does not end in 0, the version is parsed properly. This only affects IndexV2.

This seems to affect latest_version, arp_min_version, and arp_max_version

For example -

• 128.0 -> 128
• 11.10 -> 11.1

My best guess is that the version information isn't being handled explicitly as a string. When there is only a single decimal point, it then gets parsed as a number
