Use strings.ToLower so any casing (configMaps, ConfigMaps, sEcrets)
normalizes to the canonical lowercase ResourceMap key, and simplify the
flag help text. Addresses PR review feedback.

PR #1061 renamed the configmap key in kube.ResourceMap from "configMaps"
(camelCase) to "configmaps" (lowercase) to fix controllers not being
able to mark themselves as initialized. However, two callers were not
updated to match the new canonical key:
1. The Helm chart's deployment template still emits
`--resources-to-ignore=configMaps` (camelCase) when
`reloader.ignoreConfigMaps: true` is set.
2. The validation in `GetIgnoredResourcesList` only accepts the legacy
camelCase spelling.
Because `ignoredResourcesList.Contains(k)` uses case-sensitive string
equality, the lookup against the new lowercase ResourceMap key never
matches. The configmaps controller is created and starts watching
ConfigMaps cluster-wide, even though the chart's ClusterRole template
(also gated on `ignoreConfigMaps`) does not grant permission for it.
The resulting pod logs are full of:
configmaps is forbidden: User "system:serviceaccount:reloader:reloader-reloader"
cannot list resource "configmaps" in API group "" at the cluster scope
This change:
- Updates the chart deployment template to emit the canonical lowercase
`configmaps` value.
- Normalizes the input in `GetIgnoredResourcesList`, accepting both
`configMaps` (legacy, for backward compatibility with users who pass
the flag directly) and `configmaps` (canonical), and emitting the
canonical form to the caller.
- Updates the flag help text and adds tests covering both spellings.
