Bump version to 5.5.0

This appears to be the same issue as 70df3d54f3.
Hopefully the next MinGW update will remove the need for this.

+### Important note about automated GitHub checks
+
+When you submit a pull request, GitHub automatically runs checks on the Minetest
+Engine combined with your changes. One of these checks is called 'cpp lint /
+clang format', which checks code formatting. Because formatting for readability
+requires human judgement this check often fails and often makes unsuitable
+formatting requests which make code readability worse.
+
+If this check fails, look at the details to check for any clear mistakes and
+correct those. However, you should not apply everything ClangFormat requests.
+Ignore requests that make code readability worse and any other clearly
+unsuitable requests. Discuss in the pull request with a core developer about how
+to progress.

+## Concept approvals and roadmaps
+
+If a Pull Request is not a bug fix:
+
+* If it matches a goal in [the roadmap](../doc/direction.md), then the PR should
+  be labelled as "Roadmap" and the goal stated by number in the description.
+* If it doesn't match a goal, then it needs to receive a concept approval within
+  a week of being opened to remain open. This 1 week deadline does not apply to
+  PRs opened before the roadmap was adopted; instead, they may remain open or be
+  closed as needed. Use the "Concept Approved" label. Issues can be marked as
+  "Concept Approved" to give preapproval to future PRs.

+- If you build a bare server you don't need to have the Irrlicht or IrrlichtMt library installed.
+  - In that case use `-DIRRLICHT_INCLUDE_DIR=/some/where/irrlicht/include`.
+
+- Minetest will use the IrrlichtMt package that is found first, given by the following order:
+  1. Specified `IRRLICHTMT_BUILD_DIR` CMake variable
+  2. `${PROJECT_SOURCE_DIR}/lib/irrlichtmt` (if existent)
+  3. Installation of IrrlichtMt in the system-specific library paths
+  4. For server builds with disabled `BUILD_CLIENT` variable, the headers from `IRRLICHT_INCLUDE_DIR` will be used.
+  - NOTE: Changing the IrrlichtMt build directory (includes system installs) requires regenerating the CMake cache (`rm CMakeCache.txt`)

 - `curl` is optional, but required to read the serverlist, `curl[winssl]` is required to use the content store.
 - `openal-soft`, `libvorbis` and `libogg` are optional, but required to use sound.
-- `freetype` is optional, it allows true-type font rendering.
 - `luajit` is optional, it replaces the integrated Lua interpreter with a faster just-in-time interpreter.
+- `gmp` and `jsoncpp` are optional, otherwise the bundled versions will be compiled
 
 There are other optional libraries, but they are not tested if they can build and link correctly.
