Update NATS server and chart

[adampie]

I'm working on adding tests in #47 and ran into this issue -> nats-io/nats-server#5210

On MacOS

• ✅ Tests pass without race detection
• ❌ Tests fail with -race flag

  go test -race ./pkg/hooks_stream
  # Results in: fatal error: checkptr: converted pointer straddles multiple allocations

Error Details

  fatal error: checkptr: converted pointer straddles multiple allocations

  goroutine 20 gp=0xc00008ae00 m=0 mp=0x1017f6060 [running]:
  runtime.throw({0x1010d5d1a?, 0xc0001e6f68?})
  runtime.checkptrAlignment(0x1010ab026?, 0xa?, 0x0?)

We should update NATS as we're a bit behind.
