Fix account management lambdas in v3.2

**Why?**

Issue: #728

With the latest Python runtime update provided by AWS Lambda, the boto3
dependencies were upgraded. However, with the account management Lambda
functions, the `aws-xray-sdk` requires botocore v1.29.54. This version
is incompatible with the latest boto3 package that was added to the Lambda
function runtime. Hence, it returned an error as described in 728.

**What?**

To ensure compatible versions are installed, ADF's lambda functions should
set the specific version of boto3 in its requirements.txt file if they rely on
that.
