[serialization] [tests] [java]`ci.json` creation obstructed by `checkFoo` unit tests
Reproduction:
```bash
git clone --recursive https://github.com/kaitai-io/kaitai_struct.git && cd kaitai_struct

for module in $(git submodule status | awk '{print $2}')
do
    pushd $module
    git checkout serialization
    popd
done

cd tests && ./build-compiler && ./build-formats && ./ci-java
```
We get something like this:
```
/Users/izmar/git/tmp/kaitai_struct/tests/aggregate/junit_xml_parser.rb:37:in `block (2 levels) in each_test': Unable to parse name: "checkSizeMismatchCheckOrWrite" (RuntimeError)

	from aggregate/convert_to_json:77:in `<main>'
```

In `junit_xml_parser.rb` change
```ruby
raise "Unable to parse name: \"#{name}\"" unless name =~ /^[Tt]est(.*?)$/
```
to
```ruby
raise "Unable to parse name: \"#{name}\"" unless (name =~ /^[Tt]est(.*?)$/ || name =~ /^[Cc]heck(.*?)$/)
```
and we can `cat test_out/java/ci.json` again.

This is what I'm doing while working on https://github.com/kaitai-io/kaitai_struct/issues/1060#issuecomment-1656758179.
