StsClientConfigurationExtension doesn't resolve secret from Vault

[hemantxpatel]

Describe the bug

A clear and concise description of what the bug is.
StsClientConfigurationExtension.java expects a clientId / clientSecretAlias but doesn't resolve the secret from Vault.

tractusx-edc/edc-extensions/dcp/tx-dcp-sts-dim/src/main/java/org/eclipse/tractusx/edc/iam/dcp/sts/StsClientConfigurationExtension.java

Lines 62 to 74 in b618350

	var clientSecretAlias = context.getConfig().getString(CLIENT_SECRET_ALIAS, null);
	var monitor = context.getMonitor().withPrefix("STS Client for DIM");
	if (tokenUrl == null) {
	missingMandatoryProperty(monitor, TOKEN_URL);
	}
	if (clientId == null) {
	missingMandatoryProperty(monitor, CLIENT_ID);
	}
	if (clientSecretAlias == null) {
	missingMandatoryProperty(monitor, CLIENT_SECRET_ALIAS);
	}
	return new StsRemoteClientConfiguration(tokenUrl, clientId, clientSecretAlias);

To Reproduce

Steps to reproduce the behavior:

1. Use STS Remote Client in EDC and make a query catalog request.
2. Oauth Request to STS fails with 401 due to invalid client id / secret.

Expected behavior

A clear and concise description of what you expected to happen.
It should resolve secrets from vault. Similar configuration exists in eclipse-edc/Connector repo which resolves the secret from Vault.

StsRemoteClientConfigurationExtension.java#L61-L64

var clientSecret = vault.resolveSecret(clientSecretAlias);
Objects.requireNonNull(clientSecret, format("Client secret could not be retrieved from the vault with alias %s", clientSecretAlias));

return new StsRemoteClientConfiguration(tokenUrl, clientId, clientSecret);
