Update CLI not found error message

[siamaksade]

The current error message when the Tekton CLI is not found is:

Cannot find A CLI for interacting with Tekton v0.6.0.

Tekton v0.6.0 is in correct given that 0.6.0 is the version of the CLI. It should possibly say instead:

Cannot find Tekton CLI v0.6.0 for interacting with Tekton Pipelines.

We need to handle that by changing regexp

vscode-tekton/src/tools.ts

Line 124 in 0babd12

const version = new RegExp(`^Client version:\\s([0-9]+\\.[0-9]+\\.[0-9]+)$`);

to have optional v before version.
tektoncd/cli#604

This is just about the wording of the error message. Tekton CLI v0.6.0 vs Tekton 0.9

Yes, sorry. Message fixed with this commit 8bb4883
