feat(temperature): %temperature-k% token for Kelvin (#2784) 

* added kelvin option for module/temperature

* changelog for the changes i made

* fixed typos

* fixed the temperature conversion to be more precise

* Update CHANGELOG.md

Co-authored-by: Patrick Ziegler <p.ziegler96@gmail.com>

* changed the calculation of the different temperatures

it now uses float as a initial value and makes m_temp temp_k and temp_f by converting and rounding with std::round

* std::lround makes more sense to use than std::round

@ -19,6 +19,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- `custom/text`: The `content` setting and all its properties are deprecated in favor of `format` with the same functionality. ([`#2676`](https://github.com/polybar/polybar/pull/2676))
### Added
- `internal/temperature`: `%temperature-k%` token displays the temperature in kelvin ([`#2774`](https://github.com/polybar/polybar/discussions/2774), [`#2784`](https://github.com/polybar/polybar/pull/2784))
- `internal/pulseaudio`: `reverse-scroll` option ([`#2664`](https://github.com/polybar/polybar/pull/2664))
- `custom/script`: Repeat interval for script failure (`interval-fail`) and `exec-if` (`interval-if`) ([`#943`](https://github.com/polybar/polybar/issues/943), [`#2606`](https://github.com/polybar/polybar/issues/2606), [`#2630`](https://github.com/polybar/polybar/pull/2630))
- `custom/text`: Loads the `format` setting, which supports the `<label>` tag, if the deprecated `content` is not defined ([`#1331`](https://github.com/polybar/polybar/issues/1331), [`#2673`](https://github.com/polybar/polybar/pull/2673), [`#2676`](https://github.com/polybar/polybar/pull/2676))
