Bug 33134: Add some 76 missing languages

When languages come into facets in ES, Koha should know
the names for the codes used records.  Otherwise
the three-letters language code is being displayed in
the facet instead of name.  Koha now knows about 77
languages, many are still missing.

The most missed 76 languages, in order of occurrences
in my data sets, are (MARC 21 codes): grc, syr, chu, cop, arc,
ang, epo, syc, gez, sla, san, csb, akk, gmh, egy, wen, gle,
fro, rom, mac, mal, uga, mis, sem, sux, pli, bos, che, dum,
kaz, tib, enm, frm, mlt, got, nds, ira, lin, uzb, ave, cho,
jrb, bnt, pal, tut, goh, hsb, inc, mlg, roa, cel, sam, bem,
fur, gem, hit, lad, nah, ota, peo, pro, tat, wel, yor, bra,
den, hau, her, kas, mga, myn, nya, pra, que, tir, tuk.

Plus: gwi, dgr, chp asked in bug 23693.

Here, I do not put language codes which are extremely rare
in my data sets.

Subtags and names for language_subtag_registry are taken from
https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry,
English names for language_descriptions.description - from
https://www.loc.gov/marc/languages/language_code.html, and Polish names -
from https://przepisy.bn.org.pl/aneksy#25-kody-jezykow---marc-21.

Test plan:
==========
1. Hava a ES installation with reasonable number of records,
   with a variety of languages in 008/35-39 not present in
   Koha (you can modify your record with codes from the list above).
   Set FacetMaxCount to a high number (like 500 or so,
   dependiing on the size of your data set).
2. Do a search, like '*a*'.
3. Controll the content of the Language faset -- you should
   see some bare codes instead of language names.
4. Apply the patch -- update the database.
5. Perform the same search.
6. You should see the names in place of the codes.
7. Optionally, you can activate the Polish translation and
   you should be able to see Polish names for the added languages.
