fix: maven staging timeout (#1737)

Maven staging often takes longer than the default 5 minutes. Increase to 10.

Currently we are seeing the following error:

```console
Waiting for operation to complete...
....................................................................................................
[WARNING] TIMEOUT after 302.4 s
[ERROR] Rule failure while trying to close staging repository with ID "softwareamazon-7956".
[ERROR] 
[ERROR] Nexus Staging Rules Failure Report
[ERROR] ==================================
[ERROR] 
[ERROR]

[ERROR] Cleaning up remote stage repositories after a Rule failure during close of staging repositories: []
[ERROR]  * Dropping failed staging repository with ID "softwareamazon-7956" (Rule failure during close of staging repositories: []).
```

### Side note

We already implemented this change years ago in publib, we should really switch over to publib.

See cdklabs/publib#30
