Error installing MySQL Shell (>= 8.0.30 (included 8.1.1))

[wchiquito]

Describe the bug
After installing MySQL Shell and trying to run it an error message is displayed.

To Reproduce
Steps to reproduce the behavior:

1. Run the commands:
   1.1 $ dbdeployer unpack mysql-8.1.0-linux-glibc2.17-x86_64-minimal.tar.xz
   1.2 $ dbdeployer unpack --shell mysql-shell-8.1.1-linux-glibc2.28-x86-64bit.tar.gz --target-server=8.1.0
   1.3 $ dbdeployer deploy single 8.1
   1.4 $ sandboxes/msb_8_1_0/mysqlsh
2. See error:
   ~/opt/mysql/8.1.0/libexec/mysqlsh: libexec folder not found, shell installation likely invalid

Expected behavior
Running MySQL Shell.

Environment:

• OS: Linux Mint 21.2 (GNU/Linux)
• dbdeployer version: 1.73.0
• Tarballs origin: https://dev.mysql.com/downloads/

Additional coment
Manually copying the libexec folder from mysql-shell-8.1.1-linux-glibc2.28-x86-64bit.tar.gz (after unpacking) to ~/opt/mysql/8.1.0/ everything works as expected.
