feat(client): overwrite client context instead of setting new one (backport #20356)

[mergify]

Description

Closes: #XXXX

CreateExecuteContext already sets the client context, we don't need to create a new instance

func CreateExecuteContext(ctx context.Context) context.Context {
	srvCtx := server.NewDefaultContext()
	ctx = context.WithValue(ctx, client.ClientContextKey, &client.Context{})
	ctx = context.WithValue(ctx, server.ServerContextKey, srvCtx)

	return ctx
}
