Git-machete

- Fixed: visual regression since 2023.3: branches and commits were squeezed too tightly vertically

- Added: support for IntelliJ 2023.3.

- Fixed: all `com.intellij.diagnostic.PluginException: ... ms to call on EDT ...update...` errors, hopefully for good (reported by itxshakil)

- Fixed: more `com.intellij.diagnostic.PluginException: ... ms to call on EDT ...update...` errors (reported by itxshakil)

- Fixed: `com.intellij.diagnostic.PluginException: ... ms to call on EDT ...update...` errors due to loading of classes from action update

- Dropped support for IntelliJ 2022.1.
Note that the versions of this plugin published so far will remain available for download in IntelliJ 2022.1 indefinitely.
The change in the range of supported IntelliJ versions will only affect the new plugin releases, starting from this one.
- Added support for IntelliJ 2023.2.
- Added support for `machete-post-slide-out` hook (see [CLI docs](https://git-machete.readthedocs.io/en/stable/#hooks)).
