Subject: [PATCH] fix(types): narrow tag_color type to supported color literals

Replace `string` with `'red' | 'yellow' | 'green' | 'gray' | 'blue'`
for `tag_color` in EntityTypedField, EntityStringField, and
EntityCustomField to match the Slack API specification.

Per https://docs.slack.dev/messaging/work-objects/#supported-properties-for-a-field:
Can only be set when the type is string. Allows the string to be
highlighted in one of the following colors: red, yellow, green, gray,
blue. e.g., tag_color: "red".
