Dynamic paths for tools and removal of unused book endpoints (#3018)

# Description of Changes

This pull request includes several changes primarily focused on
improving configuration management, removing deprecated methods, and
updating paths for external dependencies. The most important changes are
summarized below:

### Configuration Management Improvements:
* Added a new `RuntimePathConfig` class to manage dynamic paths for
operations and pipeline configurations
(`src/main/java/stirling/software/SPDF/config/RuntimePathConfig.java`).
* Removed the `bookAndHtmlFormatsInstalled` bean and its associated
logic from `AppConfig` and `EndpointConfiguration`
(`src/main/java/stirling/software/SPDF/config/AppConfig.java`,
`src/main/java/stirling/software/SPDF/config/EndpointConfiguration.java`).

### External Dependency Path Updates:
* Updated paths for `weasyprint` and `unoconvert` in
`ExternalAppDepConfig` to use values from `RuntimePathConfig`
(`src/main/java/stirling/software/SPDF/config/ExternalAppDepConfig.java`).

### Minor Adjustments:
* Corrected a typo from "Unoconv" to "Unoconvert" in
`EndpointConfiguration`
(`src/main/java/stirling/software/SPDF/config/EndpointConfiguration.java`).
