bug: tool name sanitization

[mgrechukh]

Describe the Bug

In pre-0.16.0 shell implementation, tool name consisting of multiple words separated by dash were sanitized as environment variable. I.e. for "teleport-community" plugin we expect "ASDF_TELEPORT_COMMUNITY_VERSION".

As now toolName passed uppercased but otherwise unmodified, it now awaits "ASDF_TELEPORT-COMMUNITY_VERSION" variable which can not be simply set in shell. It breaks certain automated usage scenarios.

Here's the proposed fix: #2194

Steps to Reproduce

1. export ASDF_TELEPORT_COMMUNITY_VERSION=14.3.4
2. asdf exec tsh version

Expected Behaviour

❯ asdf exec tsh version
Teleport v14.3.4 git:v14.3.4-0-g16b0227 go1.21.6

Actual Behaviour

❯ asdf exec tsh version
Teleport v9.3.26 git:api/v9.3.26-0-ga7c726f670 go1.17.11
