Adopt version 0.0.17 of the language server

[rcjsuen]

Previously, version 0.0.14 was adopted in #233 but two bugs were discovered that caused the change to be reverted. These two issues have now been fixed in 0.0.17.

• Invalid error after editing Dockerfile caused by incorrect handling of changes from textDocument/didChange rcjsuen/dockerfile-language-server#216
• Linter flags COPY's closing JSON bracket as an invalid argument rcjsuen/dockerfile-language-server#217

Two other issues (#237 and #238) unrelated to the 0.0.14 upgrade were reported and they have also been implemented and fixed. And of course, #218 that was fixed in 0.0.14 has not regressed and is fixed in 0.0.17.

Please use the following Dockerfile to test the update to 0.0.17 from 0.0.13. Thank you!
