Long TXT records always require re-creation v 2.0.0-rc1

[wiggly]

So, for TXT records over a certain length DNS requires them to be split and the record comes back split from the GANDI API.

This means that for things like DKIM records, even if you add quotes into the string the resource always appears to require re-creation.

Example record with dummy data to show the TF outut on plan;

  # gandi_livedns_record.test_long_txt_menutia_io will be updated in-place
  ~ resource "gandi_livedns_record" "test_long_txt_menutia_io" {
        id     = "menutia.io/_long_text/TXT"
        name   = "_long_text"
        ttl    = 3600
        type   = "TXT"
      ~ values = [
          - "\"012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789\" \"01234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789\"",
