pkg/js: fix readme for pkg/js and prepare another release

CHANGELOG.md

 ## 1.14.0
 
 ### Core library changes
 * `dart:math`
   * `Random` added a `secure` constructor returning a cryptographically secure
     random generator which reads from the entropy source provided by the
     embedder for every generated random value.

 * `dart:core`
   * `Uri` added `removeFragment` method.
   * `String.allMatches` (implementing `Pattern.allMatches`) is now lazy,
     as all `allMatches` implementations are intended to be.
   * `Resource` is deprecated, and will be removed in a future release.
 
 * `dart:developer`
   * Added `Timeline` class for interacting with Observatory's timeline feature.
   * Added `ServiceExtensionHandler`, `ServiceExtensionResponse`, and `registerExtension` which enable developers to provide their own VM service protocol extensions.

 * `dart:io`
   * **Breaking:** Secure networking has changed, replacing the NSS library
     with the BoringSSL library. `SecureSocket`, `SecureServerSocket`,
     `RawSecureSocket`,`RawSecureServerSocket`, `HttpClient`, and `HttpServer`
     now all use a `SecurityContext` object which contains the certificates
     and keys used for secure TLS (SSL) networking.
 
     This is a breaking change for server applications and for some client
     applications. Certificates and keys are loaded into the `SecurityContext`
     from PEM files, instead of from an NSS certificate database. Information

     * The deprecated `ServerSocketReference` and `RawServerSocketReference`

 * This is the last release to ship the VM's "legacy debug protocol".
   We intend to remove the legacy debug protocol in Dart VM 1.14.
 
 * The VM's Service Protocol has been updated to version 3.0 to take care
   of a number of issues uncovered by the first few non-observatory
   clients.  This is a potentially breaking change for clients.

     they will keep the Dart process alive until they time out. This fixes the
     handling of persistent connections. Previously, the client would shut down
     immediately after a request.
 
   * **Breaking change:** `HttpServer` no longer compresses all traffic by
     default. The new `autoCompress` property can be set to `true` to re-enable
     compression.
 
 * `dart:isolate`: `Isolate.spawnUri` added the optional `packageRoot` argument,
   which controls how it resolves `package:` URIs.
