feat: support parameter handling for dynamic URL paths (#35)

- Comment out unused form data encoding in `post` method
- Remove redundant error logging in `post` method
- Add conditional URL path selection in `trigger` method based on parameters
- Add `parameter` flag to CLI options in `main.go`
- Include `parameter` in the `run` function configuration
- Import `net/url` package in `plugin.go`
- Add `Parameter` field to `plugin.go` struct
- Parse and add parameters to URL values in `Exec` method
- Pass parsed parameters to `trigger` method in `Exec` function
