weatherreport show error when execute

[NOTE]: # ( ^^ Provide a general summary of the issue in the title above. ^^ )

## Description
Regarding to the ticket( https://github.com/apache/couchdb/issues/4747 ) I wanted to use a diagnostic tool
weatherreport

when I executed this it shows

in /opt/couchdb/bin
./weatherreport
/usr/bin/env: ‘escript’: No such file or directory

so I appended the
PATH=$PATH:/opt/couchdb/erts-12.3.2.10/bin

and it got
{"init terminating in do_boot",{'cannot get bootfile','no_dot_erlang.boot'}}
init terminating in do_boot ({cannot get bootfile,no_dot_erlang.boot})

## Expected Behaviour

1) expecting weatherrepot runs smoothly

## Your Environment

* CouchDB version used:
couchdb-3.3.2-1.el8 in RHEL8 packages
* Operating system and version:
2 * Intel(R) Xeon(R) Gold 6240 CPU @ 2.60GHz
Mem 4G
Red Hat Enterprise Linux release 8.8 (Ootpa)(4.18.0-477.10.1.el8_8.x86_64)

Start by reproducing the command from /opt/couchdb/bin/weatherreport in the stated CouchDB 3.3.2 RHEL 8 environment, then inspect how this entry point locates escript and the Erlang boot files. Done means weatherreport runs without manually modifying PATH and produces its diagnostic output.
