Add bitnami common lib as a dependency

[jklemm]

Details

Starting with PR #45, a dependency on the Bitnami "common" library was added.

There are two issues addressing this, #101 and #116, and a solution has not yet been applied.

This PR adds the common library as a dependency of chart, thus avoiding the error below:

│ Error: malformed chart or values:
│ 	templates/:
            template:
                  chatwoot/charts/chatwoot/templates/tests/test-connection.yaml:19:20:
                  executing "chatwoot/charts/chatwoot/templates/tests/test-connection.yaml" at <include "common.tplvalues.render" (dict "value" .Values.nodeSelector "context" $)>:
                  error calling include: template: no template "common.tplvalues.render" associated with template "gotpl"

Steps to reproduce

1. Create a values.yaml at repo root.

nodeSelector:
  chatwoot: "true"

tolerations: []

postgresql:
  enabled: false
  auth:
    username: username
    postgresPassword: password
    database: chatwoot
  postgresqlHost: chatwoot
  postgresqlPort: 5432

redis:
  enabled: false
  host: host
  port: 6379

2. Run command helm template chatwoot charts/chatwoot -f values.yaml > rendered.yaml
3. Results the error:

Error: chatwoot/templates/tests/test-connection.yaml:19:20
  executing "chatwoot/templates/tests/test-connection.yaml" at <include "common.tplvalues.render" (dict "value" .Values.nodeSelector "context" $)>:
    error calling include:
template: no template "common.tplvalues.render" associated with template "gotpl"

Use --debug flag to render out invalid YAML
