fix: use singular Lithuanian form for counts like 101 and 201

[greymoth-jp]

The Lithuanian plural helper picks the wrong form for counts whose last two digits are "01" (101, 201, 301, and so on). It returns the genitive plural instead of the singular, so a 101 ms duration renders as "101 milisekundžių" instead of "101 milisekundė".

getLithuanianForm detected the singular ("one") form with:

c === 1 || (c % 10 === 1 && c % 100 > 20)

The c % 100 > 20 guard is there to exclude 11 (where Lithuanian uses the plural), but it also excludes c % 100 === 1 (101, 201, ...), which should be singular. The Latvian helper right below it already uses the correct idiom:

return c % 10 === 1 && c % 100 !== 11;

That also matches the CLDR Lithuanian rule, where one is i % 10 = 1 and i % 100 != 11..19; for the integer counts handled here that reduces to i % 10 === 1 && i % 100 !== 11. So 1, 21, 31, ..., 101, 121 are singular and 11, 111, 211 stay plural.

This reuses that idiom for Lithuanian. The counts that were already correct (1, 21 through 91, and 11..19) are unchanged; only 101, 201, ..., 901 move from the plural to the singular form.

Also added two rows to test/definitions/lt.tsv (101 -> singular, 211 -> still plural) and a HISTORY.md entry.
