Fix build command

[wbt]

Description

This partially addresses long-broken parts of the npm testing scripts this PR template requires that contributors complete.
It doesn't fully address all the issues (e.g. that docker is an undocumented dependency required to run the geth instamine script which is triggered by one of the commands below, but things get much farther along than they used to.

Type of change

• Bug fix (non-breaking change which fixes an issue)

Checklist:

• I have selected the correct base branch.
• I have performed a self-review of my own code.
• I have commented my code, particularly in hard-to-understand areas.
• I have made corresponding changes to the documentation.
• My changes generate no new warnings.
• Any dependent changes have been merged and published in downstream modules. [There are none]
• I ran npm run dtslint with success and extended the tests and types if necessary.
• I ran npm run test:unit with success.
• I ran npm run test:cov and my test cases cover all the lines and branches of the added code. [This works better now, but still not 100%]
• I ran npm run build and tested dist/web3.min.js in a browser.
• I have tested my code on the live network.
• I have checked the Deploy Preview and it looks correct. [I'm not sure what this refers to or how to do this; further instructions could be helpful.]
• I have updated the CHANGELOG.md file in the root folder.

💛 - Coveralls

[wbt]

The e2e_windows CI step is broken due to the same inability to connect to Infura that holds up other PRs.
The unit_and_e2e_clients CI step failed due to a short timeout that appears to be just unreliability in tests, where random failures of that type are observed locally and usually fixed by re-running the test, not something I have permissions to do in this repository. The coveralls report seems broken, falsely reporting lines as losing coverage when this PR shouldn't affect that metric.

This somehow was automatically closed, but #4861 supersedes this anyways
