Localisation issues in `sk.js` (Slovak)

Related #302 #4

---

There are some issues in sk.js:

• ordinal: n => `${n}º`, → ordinal: n => `${n}.`,:
  • there should a dot after ordinal numbers;
• L: 'DD.MM.YYYY', → L: 'DD. MM. YYYY',:
  • according to STN 01 6910 (in Slovak), the spaces after each dot in the date is prefered, but the spaces can be omitted, therefore this is not an issue per se;
• weekdays: 'Nedeľa_Pondelok_Utorok_Streda_Štvrtok_Piatok_Sobota'.split('_'), → weekdays: 'nedeľa_pondelok_utorok_streda_štvrtok_piatok_sobota'.split('_'),
• weekdaysShort: 'Ne_Po_Ut_St_Št_Pi_So'.split('_'), → weekdaysShort: 'ne_po_ut_st_št_pi_so'.split('_'),.

Then there is as an issue with the the numbers of and declension of the nouns (see also #302). The grammatical rules in Slovak are quite similar to those in Czech, therefore I have just copied the plural() and translate() functions from there and replaced the nouns with the Slovak ones. I would open a PR with this, but I am not a good coder, therefore this must be reviewed.

All in all, here is the proposed content of sk.js. I hope I did not made any mistakes. I have added some comments to make it easier to check if the words are really those that should be assigned to the particular key.

sk.js

// Slovak [sk]
import dayjs from 'dayjs'

function plural(n) {
  return (n > 1) && (n < 5) && (~~(n / 10) !== 1) // eslint-disable-line
}

/* eslint-disable */ 
function translate(number, withoutSuffix, key, isFuture) {
  const result = `${number} `
  switch (key) {
    case 's': // a few seconds / in a few seconds / a few seconds ago
      // in a few seconds / a few seconds ago
      return (withoutSuffix || isFuture) ? 'pár sekúnd' : 'pár sekundami'

        return result + (plural(number) ? 'minúty' : 'minút')

PS—@prantlf, can I ask you to check the translate() function? Thanks in advance! 😃
