"make renode" is broken -- due to Verilator 5.006?

After updating renode, and entering the conda env with "make enter", I get an error when attempting "make renode" in any of the project directories:

```

If I specify an older Verilator package in `conf/environment.yml`, 5.004 or before, it works ok.

These worked:
```
- litex-hub::verilator=5.004_11_g51de2c919=20221206_125647
- litex-hub::verilator=5.004_64_gff2f711d0=20230116_180937
```
These didn't work:
```
- litex-hub::verilator=5.006_99_g45f955f17=20230218_072610
- litex-hub::verilator=5.006_94_g026bbc306=20230214_175409
- litex-hub::verilator
```

FYI @PiotrZierhoffer @proppy -- have there been any changes to the conda-eda package for Verilator?
