chore(dist): replace wget to curl to download swagger-ui (apache#2277)

Main Changes:
1. replace `wget` by `curl` when downloading `swagger-ui`
2. silence the output of `curl` and `tar` commands
3. reuse the existing `v4.15.5.tar.gz` before downloading
4. avoid downloading `swagger-ui` in non-Linux platforms to prevent build failures (there might be a cross-platform build approach available 🤔)
5. wrapp the script content within `<![CDATA[ ... ]]>` blocks ensures that the script retains its original format when generating the `dist.sh` script (also suppresses automatic indentation)
6. remove intermediate files at the end of the script

**An alternative approach**, during the generation of the `dist.sh` script, only the `${final.name}` property from the build process is utilized. It might be possible to separately store a `dist.sh` script within hugegraph-dist, then use `sed` during the build process to replace the value of `${final.name}`, **thereby avoiding the need to embed script content within the pom file**.
