Docs: Port flag description is wrong

[rangelfinal]

The port flag, used on the Listen, Run and Watch commands, is wrongly described as The PORT to listen to, can be overriden with PORT env variable, but it's actually not overriden by the PORT env variable.
The flag description should be updated to reflect the fact that the flag will override the PORT env.

ts-framework-cli/lib/commands/ListenCommand.ts

Line 18 in 731ef16

.describe("p", "The PORT to listen to, can be overriden with PORT env variable");

ts-framework-cli/lib/commands/RunCommand.ts

Line 16 in 731ef16

.describe("p", "The PORT to listen to, can be overriden with PORT env variable");

ts-framework-cli/lib/commands/WatchCommand.ts

Line 14 in 731ef16

.describe("p", "The PORT to listen to, can be overriden with PORT env variable");

The PORT environment variable should be preserved and override the port flag, for now we will fix this.

To prevent wrongful usage, maybe we should warn when the --port flag is passed with a PORT in the environment already set.
