Indented `bashExtraText` breaks xonsh, doesn't match parent indentation

[dholth]

setup-miniconda adds text to bash-like shell rc's, including .xonshrc

For .xonshrc as created by conda's initialize.py, https://github.com/conda/conda/blob/main/conda/core/initialize.py#L1564-L1576 is indented four spaces.

But a block inserted by setup-miniconda has two spaces indentation.

setup-miniconda/src/conda.ts

Lines 387 to 397 in f77e237

	// Bash profiles
	let bashExtraText: string = `
	# ----------------------------------------------------------------------------
	# Conda Setup Action: Basic configuration
	set -eo pipefail`;
	if (isValidActivate) {
	bashExtraText += `
	# Conda Setup Action: Custom activation
	conda activate "${inputs.activateEnvironment}"`;
	bashExtraText += `
	# ----------------------------------------------------------------------------`;

Unknown why this started causing failures now in the conda-libmamba-solver CI, but it did.

Probably bashExtraText has indentation "by accident" to fit into the typescript code, and should have no indentation. This would satisfy Python-based xonsh by taking bashExtraText outside of the conda initialize.py if !(test -f "{conda_exe}"): block.
