Issue created by <https://github.com/proppy|proppy>
*Description*

It looks like the default configuration for irdrop is documented as disable by default:  

<https://github.com/The-OpenROAD-Project/OpenLane/blob/00caae2b3186bb6b24a0b7db7ee1a6f056ad1702/docs/source/reference/configuration.md#L314|OpenLane/docs/source/reference/configuration.md>

Line 314 in &lt;/The-OpenROAD-Project/OpenLane/commit/00caae2b3186bb6b24a0b7db7ee1a6f056ad1702|00caae2&gt;

But the implementation seems different:  

<https://github.com/The-OpenROAD-Project/OpenLane/blob/00caae2b3186bb6b24a0b7db7ee1a6f056ad1702/configuration/general.tcl#L40|OpenLane/configuration/general.tcl>

Line 40 in &lt;/The-OpenROAD-Project/OpenLane/commit/00caae2b3186bb6b24a0b7db7ee1a6f056ad1702|00caae2&gt;

Additionally the canonical `spm` example doesn't include any configuration for `VSRC_LOC_FILES` causing the following warning:

```
2023-08-23T01:36:19.3228902Z �[32;1m01:36:19�[0m | [WARNING]: VSRC_LOC_FILES is not defined. The IR drop analysis will run, but the values may be inaccurate.
```

and ultimatly fails with the following error:

```
2023-08-23T01:36:19.3207819Z �[32;1m01:36:19�[0m | [ERROR PSM-0093] Voltage on net VDD is not set.
```

*Expected Behavior*

The default example either produce a valid irdrop report or either disable the reporting according to the documented default.

*Environment report*

```
The environment is a bit special here as I'm building openlane and its dependencies from `HEAD` as part of the <https://github.com/hdl/conda-eda> project.
```

*Reproduction material*
