17735: examples/gcoap_dtls: Increase stack size r=maribu a=maribu

### Contribution description

As the title says. The stack size was copied over from `tests/pkg_tinydtls_sock_async` cargo-cult style. Also some typos in the README were fixed.

### Testing procedure

Previously on my Nucleo-F767ZI, the CoAP client triggered the MPU stack guard on sending the DTLS hello. With this, the board no longer crashes.

### Issues/PRs references

None
