configMapGenerator: single quote removed from config map literal if quote is last character

[mloesch]

Describe the bug

When defining a literal value in configMapGenerator where the last character is a single quote, the last character is removed by kustomize build.

Files that can reproduce the issue

kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
configMapGenerator:
  - name: test
    literals:
      - TEST=this is a 'test'

Expected output

apiVersion: v1
data:
  TEST: this is a 'test'
kind: ConfigMap
metadata:
  name: test-k7hhfb697g

Actual output

apiVersion: v1
data:
  TEST: this is a 'test
kind: ConfigMap
metadata:
  name: test-k7hhfb697g

The trailing single quote is missing.

Note: if the single quote is not the last character, it works as expected:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
configMapGenerator:
  - name: test
    literals:
      - TEST=this is a 'test'.

Yields:

apiVersion: v1
data:
  TEST: this is a 'test'.
kind: ConfigMap
metadata:
  name: test-2b7bkd58k5

The fix for this one looks to have addressed another use case:

  literals: 
  - |
    sentence="Here we see the issue.

With v4.4.1:

  sentence: |
    "Here we see the issue.

Prior to v4.4.1:

  sentence: |
    Here we see the issue.
