As of version 2.296.0, if the actions runner creates a docker container to execute an action which receives github secrets as environment variables, any backslash characters in the secret values get doubled. This results in the docker container receiving an incorrect value of the secret.
Commit 01fd044 escapes all command line arguments to docker commands by replacing double-quote and backslash character with an escape sequence, which includes github secrets. This would work on unix, but the action runner dotnet framework uses the windows-native escape scheme, in which \\ is not an escape sequence in most conditions. Thus, escaped backslashes in secret values are not interpreted correctly when starting a docker process using the resulting command line arguments.
