[BUG] Key transformed to uppercase when exported to env var using wildcard

[martinsolberg]

Vault server version

v1.15.5

vault-action version

v3

Describe the bug

When getting multiple keys in a path using wildcard, the resulting environment variables have their case transformed to uppercase.

To Reproduce

with:
    secrets: |
        secret/data/ci/aws * | MYAPP_ ;

The key accessKey will be created as MYAPP_ACCESSKEY.

Expected behavior

The exported environment variable should retain the key case, e.g. MYAPP_accessKey.

Lines 11 to 13 in 77efb36

	if (isEnvVar) {
	outputKey = outputKey.toUpperCase();
	}

Why?
