Docs: Inconsistencies in Environment Variable Naming

[Tenount]

Description:
There is a small typo in the documentation where PM_API_TOKEN is mentioned instead of the correct PM_API_TOKEN_SECRET. This could lead to confusion for users.

Links:

• Code Reference: PM_API_TOKEN_SECRET
• Documentation Reference: PM_API_TOKEN

Note:
Several environment variables are not specified in the documentation, such as:

• PM_TLS_INSECURE
• PM_HTTP_HEADERS
• PM_TIMEOUT
• PM_DANGEROUSLY_IGNORE_UNKNOWN_ATTRIBUTES

It might be helpful to consider standardizing variable naming conventions to simplify support. For instance, ensuring consistency between CLI and environment variables could reduce potential confusion, as seen with the differing names like pm_proxy_server in CLI and PM_PROXY in the environment.
