[bitnami/tomcat] Fix initContainers indent

[migruiz4]

Description of the change

Fixes initContainer indent when volumePermissions.enabled=true

Possible drawbacks

None known.

Applicable issues

• fixes [bitnami/tomcat] Unable to install tomcat if an initContainers is set within a yaml value file. #29158

Additional information

The current indent works when used by itself:

initContainers:
- name: init
...

But when used in combination with volumePermissions renders into an invalid yaml caused by the indentation difference:

initContainers:
  - name: volume-permissions
     ...
- name: init
...

This PR fixes the issue by setting both indentations to 2 spaces:

initContainers:
  - name: volume-permissions
     ...
  - name: init
  ...
