remove node 10 lang server from java8 sidecars

Currently, CRW 2.13 includes typescript lang server 0.3.7 - https://github.com/redhat-developer/codeready-workspaces-images/blob/crw-2-rhel-8/codeready-workspaces-plugin-java8/build/build_node10.sh#L19
Latest is 0.8.1 - https://github.com/typescript-language-server/typescript-language-server/releases/tag/v0.8.1

We're on typescript 3.4.5: https://github.com/redhat-developer/codeready-workspaces-images/blob/crw-2-rhel-8/codeready-workspaces-plugin-java8/build/build_node10.sh#L18
Latest is 4.5.2: https://www.npmjs.com/package/typescript

So I asked...

Nick: why are we still providing node 10 based lang server in CRW? https://github.com/eclipse-che/che-devfile-registry/pull/529#issuecomment-984098394 Could we move to latest for Node 14 or 16?
Valerii: i think it's just because we haven't try to upgrade it, at least i don't see any problem with that, but we have to test new node version with all samples which use this image.
Also i think we can drop typescript and typescript-language-server https://github.com/redhat-developer/codeready-workspaces-images/blob/crw-2-rhel-8/codeready-workspaces-plugin-java8/build/build_node10.sh#L63 i don't see that we install them in upstream. @fbenoit wdyt?
Florent: yes we don't need it

So... we can remove the outdated lang server entirely.
