Incorrect documentation content in the distribution [BATCH-2676]

[spring-projects-issues]

Mahmoud Ben Hassine opened BATCH-2676 and commented

Currently, the content of the distribution includes some javascript files 3 times:

$>./gradlew dist
$>cd build/distributions/
$>unzip spring-batch-4.0.1.BUILD-SNAPSHOT-docs.zip
$>cd reference
$>tree -d -L 3

├── html
│   ├── images
│   ├── jsfiles <== correct
│   └── tocbot-3.0.2 <== correct
├── jsfiles <== Incorrect (not needed here)
├── pdf
│   ├── jsfiles <== Incorrect (not needed here)
│   └── tocbot-3.0.2 <== Incorrect (not needed here)
└── tocbot-3.0.2 <== Incorrect (not needed here)

These javascript files are only needed for the html version.
