eos_cli_config_gen: errdisable documentation J2 expects recovery.interval to be always set

[alexeygorbunov]

Issue Summary

Documentation template python-avd/pyavd/_eos_cli_config_gen/j2templates/documentation/errdisable.j2 unconditionally accesses errdisable.recovery.interval without trying to confirm it's existence or to set a default value (defined in schema but not implemented in J2):

{%         if errdisable.recovery.interval is arista.avd.defined %}
{%         endif %}
{%         if errdisable.recovery.causes is defined %}
|  Detect Cause | Enabled | Interval |
| ------------- | ------- | -------- |
{%             for cause in errdisable.recovery.causes | arista.avd.natural_sort %}
{%                 if cause == 'arp-inspection' %}
| {{ cause }} | True | {{ errdisable.recovery.interval }} |
{%                 elif cause == 'bpduguard' %}
...
