Issue Description

After experiencing the AzureRmWebAppDeployment@4 task being broken at least twice, we decided to lock it in our YAML pipelines to version 4.225.1. Due to the Node 10 deprecation warning, we are now attempting to update to the latest version.

We have found that when using the AdditionalArguments parameter and supplying MSDeploy arguments of form -setParam:name='X',value='Y' we are experiencing a bug. This appears to be logic that was introduced in 88ec513 related to encoding.

The change in behaviour has connection strings that were previously correctly encoded as:

Encrypt=True;TrustServerCertificate=False;Data Source=some-sql-server.database.windows.net,1433;Initial Catalog=some-database;User Id=someuser;Password=somepassword;

To now be incorrectly encoded as:

'Encrypt=True;TrustServerCertificate=False;Data Source=some-sql-server.database.windows.net",1433;Initial Catalog="some-database;User Id=someuser;Password=somepassword;'

Please note the following breaking changes:

1. Invalid insertions of "
2. Invalid prefix and suffix of single quote marks
