feat(devin-lang): add support for writing content to a file #101

The commit introduces a new feature to the devin-lang extension, allowing users to write content to a file using the `write` command. This command enables the modification of files within the development environment, enhancing the language's capabilities for file manipulation. The syntax for the `write` command is specified as `/write:/path/to/file:L1-C2`, where the path points to the file to be written to, and the line and column numbers define the range of content to be replaced. This feature is implemented in `BuiltinAgentProvider.kt` by adding a new entry for the `WRITE` command, and two new test cases are added to `DevInParsingTest.kt` to ensure its correct functionality.
