fix: prompt component display names and code of starter templates

[viktoravelino]

Jira LE-159

This pull request updates the templates starter project to consistently use the name "Prompt Template" instead of "Prompt" for relevant components. It also updates the underlying code for the PromptComponent to reflect this naming and removes the unused "mode" input field, streamlining the configuration and improving clarity.

Component naming and configuration updates:

• Renamed all instances of display_name and name from "Prompt" to "Prompt Template" for prompt-related components in the starter project configuration. [1] [2] [3] [4]

Component code and field updates:

• Updated the embedded Python code for the PromptComponent to use "Prompt Template" as its display_name and name, and removed the "mode" input field, relying instead on the use_double_brackets boolean for template syntax selection.

Summary by CodeRabbit

• Refactor
  • Updated naming of Prompt component to "Prompt Template" across all starter project templates for improved clarity.
  • Removed optional mode configuration controls from Prompt components across multiple starter projects, simplifying the user interface.

For posterity: Checked with Viktor to verify if there are any templates not covered that need this change as well. Changes looks good otherwise.
