[PATCH] fix: use values that are representable as double in test

Values like 0.1 are not representable as a double which can result in
problems, for example:

```
[...]/dune/common/test/hybridutilitiestest.cc:114:43: error: static assertion failed: Wrong compile time sum!
  114 |   static_assert(sum(numberTupleConstexpr) == 5.1, "Wrong compile time sum!");
      |                 ~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~
[...]/dune/common/test/hybridutilitiestest.cc:114:43: note: the comparison reduces to ‘(5.09999999999999964473e+0l == 5.09999999999999999991e+0l)’
```

with [gcc 13.2.0 on i386][1].
