doc: add lua API changes

I intentionally didn't mark the function names as code or similar,
as changing formatting every other word seemed too visually distracting.

Significant Lua API changes
Incompatible changes since 3.0.0
In the main ``kres.*`` lua binding, there was only change in struct knot_rrset_t:
- constructor now accepts TTL as additional parameter (defaulting to zero)
- add_rdata() doesn't accept TTL anymore (and will throw an error if passed)
In case you used knot_* functions and structures bound to lua:
- knot_dname_is_sub(a, b): knot_dname_in_bailiwick(a, b) > 0
- knot_rdata_rdlen(): knot_rdataset_at().len
- knot_rdata_data(): knot_rdataset_at().data
- knot_rdata_array_size(): offsetof(struct knot_data_t, data) + knot_rdataset_at().len
- struct knot_rdataset: field names were renamed to .count and .rdata
- some functions got inlined from headers, but you can use their kr_* clones:
kr_rrsig_sig_inception(), kr_rrsig_sig_expiration(), kr_rrsig_type_covered().
Note that these functions now accept knot_rdata_t* instead of a pair
knot_rdataset_t* and size_t - you can use knot_rdataset_at() for that.
- knot_rrset_add_rdata() doesn't take TTL parameter anymore
- knot_rrset_init_empty() was inlined, but in lua you can use the constructor
- knot_rrset_ttl() was inlined, but in lua you can use :ttl() method instead
- knot_pkt_qname(), _qtype(), _qclass(), _rr(), _section() were inlined,
but in lua you can use methods instead, e.g. myPacket:qname()
- knot_pkt_free() takes knot_pkt_t* instead of knot_pkt_t**, but from lua
you probably didn't want to use that; constructor ensures garbage collection.
