Fix capitalization of openmoji_tags in data files

[waldyrious]

In addition to the capitalization changes, the following minor tweaks were made:

• Fixed typo ("punctation" → "punctuation") in openmoji_tags of U+2753, U+2754, U+2755, and U+2757
• Adjusted openmoji_tags of U+1F919: "shaka" → "shaka sign", and add "hang loose", "right on" (from Wikipedia: https://en.wikipedia.org/wiki/Shaka_sign)
• Split first entry of U+1F44E's openmoji_tags: "dislike no" → "dislike, no" (to match "like, yes" in U+1F44D)
• Reordered openmoji_tags of HAL 9000 (25C9-FE0F-200D-1F534-200D-25AE-FE0F)
• Removed "lisa schulz, julian grüneberg" from the openmoji_tags of U+1F4AA

Note for reviewers: the changes are best viewed (i.e. more readable) in the data/openmoji.json or index-list.html file, in unified diff mode.
