Use template functions to quote env vars

[mcquinne]

This allows helm to intelligently quote env var values, e.g. in order to pass json arrays as values

What I am changing

• The way that helm-chart/eoapi/templates/services/configmap.yaml was rendering envValues prevented it from handling strings representing JSON arrays, which are used in several places for eoapi services.
• For example, setting TIPG_DB_SCHEMAS: '["public", "pgstac"]' as described in the docs results in:
  • Error: UPGRADE FAILED: YAML parse error on eoapi/templates/services/configmap.yaml: error converting YAML to JSON: yaml: line 8: did not find expected key

How I did it

• Using the builtin quote template function intelligently quotes input strings to prevent repeated, unescaped double-quotes

How you can test it

• Set TIPG_DB_SCHEMAS: '["public", "pgstac"]' in values.yaml under vector.settings.envVars and run make deploy
